There are three main reasons for oxidation of stainless steel: production process, which is one of the reasons for oxidation of steel products. In terms of production process and product characteristics, forming a thin oxide film on the product surface is the basic process to avoid oxidation, and it is also one of the main characteristics of steel products different from other steel products. It is specialized in products, renewable resources business and business package Including: stainless steel plate, stainless steel coil, stainless steel belt and stainless steel pipe. However, when the oxide film is incomplete and discontinuous due to insufficient or negligent production process, the oxygen in the air will directly react with some elements in the product, resulting in the appearance of oxidation of the product.Model & mdash; Commonly used precipitation hardening stainless steel model, usually also called -; %Cr,%Ni.Innsbruck,& Ge; about thickness: cold rolled B plate (. & mdash; mm); hot rolled industrial plate No. (-mm) medium plate, chemical plate and high temperature plate; width: mm --- mm steel strip; ,InnsbruckStainless steel screen belt, , No. industrial surface and mm coil plate and flat plate surface: B smooth surface, BA (K) mirror, K mirror, K mirror, wire drawing surface and frosted surface.Stainless steel grade group Series & mdash; Chromium nickel manganese austenitic stainless steel series & mdash; Chromium nickel austenitic stainless steel model & mdash; Good ductility, used for molding products.

Rockwell hardness the Rockwell hardness test of stainless steel pipe is the same as Brinell hardness test. The difference is that it measures the depth of indentation. Rockwell hardness test is widely used at present, and HRC is second only to Brinell hardness Hb in steel pipe standards. Rockwell hardness can be used to measure metal materials from very soft to very hard, which makes up for the disadvantage of Brinell method, It is simpler than Brinell method and can read the hardness value directly from the dial of the hardness machine. However, due to its small indentation, which is mainly used for industrial transmission pipelines and mechanical structural components such as petroleum, chemical industry, medical treatment, food, light industry, when the bending and torsional strength are the same, the weight is light, so it is also widely used in all kinds of manufacturing mechanical parts and engineering structures.Construction materials shall be prepared and delivered to the site according to the data scheme, and shall be supplied according to the scheme.Inspection standard,InnsbruckPrecision stainless steel coil,W = (outer diameter wall thickness) & times; wall thickness & times; . = KGM (weight per meter). & mdash; high strength cutting tool steel, with slightly higher carbon content, can obtain higher yield strength after appropriate heat treatment, and the hardness can reach hrc. It is one of the hard stainless steels. A common application example is & ldquo; shaving blade & rdquo;. There are three common models: C and f (easy processing type).Bidirectional Product Description: the tensile strength of the material is ~ mpa, and the high working temperature can reach ℃.

The American Iron and Steel Institute uses three digits to identify various standard grades of malleable stainless steel. Among them, austenitic stainless steel is marked with numbers of and series. For example, some ordinary austenitic stainless steel is marked with and.Excellent quality,The operators are mainly plumbers and argon arc welders, with the cooperation of other types of work, and the argon arc welder shall have the certificate issued by relevant departments.National standard thickness of stainless steel pipe. Stainless steel pipe is a brand of stainless steel produced according to American ASTM standards. Before the national standard thickness of stainless steel pipe, there are stainless steel pipe national standard thickness national standard wall thickness table product name specification material price (yuan ton) rise and fall welded pipe points mm (& phi; mm) + welded pipe inch mm (& phi; mm)Typical ferritic stainless steels are Crl, Cr and Cr.Innsbruck,Measures to improve the welding quality of stainless steel pipe in order to ensure that the outer surface of stainless steel pipe is not damaged and purified, the maintenance of stainless steel pipe should be strengthened in each process of consumption, mainly including the following three aspects: the processing and consumption of stainless steel pipe should have a special consumption workshop (wood board is well used) , avoid the machining platform of austenitic stainless steel and carbon steel or solid overhead. Series & mdash; Heat resistant chromium alloy steel.The bearing capacity of decorative stainless steel pipe ice load is the main control load of offshore platform in severe cold area, a total of concrete-filled steel tubular shear members were fabricated to study the effects of outer steel pipe material, concrete strength, void ratio and shear span ratio on the shear capacity of concrete-filled steel tubular in pipe. It is found that the shear strength of members increases with the decrease of void ratio and the increase of concrete strength; The larger the shear span ratio, the smaller the shear strength. Combined with the test, the empirical formula of shear capacity of concrete-filled steel tubular in pipe is proposed, which is analyzed and verified by ABAQUS finite element modeling software. The results show that the simulation is in good agreement with the test results. In order to study the axial compression performance of stainless steel tube concrete conduit leg and the axial compression performance of stainless steel concrete conduit leg, experiments are used to verify the correctness of the finite element model. The load displacement curves of specimens in groups were compared and the effects of different void ratio, concrete strength, diameter thickness ratio and bone index on the axial compression performance of concrete-filled stainless steel tubular short columns under axial compression were analyzed. The results show that with the increase of concrete strength, the bearing capacity of specimens increases, but the ductility of specimens decreases; With the increase of void ratio and diameter thickness ratio, the bearing capacity of the specimen decreases; The bearing capacity of stainless steel tube concrete can be effectively improved by adding steel bone; Increasing the bone matching index of steel bone can improve the bearing capacity of the specimen. A compound forming process of double-layer stainless steel pipe for primary circuit main pipeline of station is designed, which solves the problem of limited length of finished products in traditional forging or casting process and meets the special requirements of complex working environment on pipeline performance. The three roll cross rolling forming process of double-layer casing with outer layer -n austenitic heat-resistant stainless steel and inner layer cr-ni martensitic heat-resistant stainless steel was simulated and optimized by using DEFORM-D finite element simulation software. The internal and external deformation, stress-strain field and temperature field of double-layer stainless steel pipe were analyzed, and the optimal deformation parameter combination was obtained by orthogonal test. The simulation results show that in the process of three roll cross rolling, the large values of equivalent stress equivalent strain and temperature are concentrated in the area between the outer tube and the roll, and the overall performance parameters of the outer tube are greater than those of the inner tube. The range analysis and variance analysis of orthogonal design test show that the optimal deformation parameter is rough rolling temperature deg; C. Feed angle & deg;, and accurately shape the end of the stainless steel pipe, so as to obtain the forged joint with better mechanical properties. According to the connection mode of the original pipe system and the plastic forming characteristics of steel pipe, a multi-step upsetting and extrusion process for the end of stainless steel pipe is proposed. The process is numerically simulated by DEFORM-D three-dimensional finite element simulation software, and the forging forming process is analyzed
