Technical Standards
High-strength stainless steel plates with excellent corrosion resistance, bending processing properties, toughness at the welding area, and stamping processing properties at the welding area, as well as their manufacturing method. Specifically, these plates contain less than 0.02% C, less than 0.02% N, and more than 11% Cr.
For stainless steel plates with 17% and appropriate contents of Si, Mn, P, S, Al, Ni, and meeting the specifications of 12≤Cr Mo 1.5Si≤17, 1≤Ni 30(C N) 0.5(Mn Cu)≤4, Cr 0.5(Ni Cu) 3.3Mo≥16.0, and 0.006≤C N≤0.030, heat treatment is required.
850 to 1250°C, followed by heat treatment with a cooling rate of over 1°C/s. This results in a microstructure containing over 12% martensite, high strength exceeding 730 MPa, corrosion resistance, and excellent bending and welding processability.
High-quality high-strength stainless steel plate. Recycled materials containing Mo, B, etc., can significantly enhance the stamping processing performance of the welding area. Oxygen-acetylene flame cannot cut stainless steel plate because stainless steel is not easily oxidized. To cut a 5CM thick stainless steel plate, a special cutting method is required.
Cutting tools processing, such as: (1) Large-wattage Laser Cutting machine, (2) Hydraulic saw machines, (3) Grinding disks, (4) Hand saws, and (5) Wire Cutting machine. Model 301 - Good ductility, suitable for...
Formed products. Can be quickly hardened through mechanical processing. Good weldability. Higher wear resistance and fatigue strength than 304 stainless steel. Model 302 - corrosion resistance similar to 304, but with better strength due to higher carbon content. Model 303 - by adding
Slight amounts of sulfur and phosphorus make it easier to machine than 304. Model 304 – Standard model; 18/8 stainless steel. GB brand number is 06Cr19Ni10. Model 309 – Better temperature resistance than 304. Model 316 – The second type after 304 to be...
Broadly used steel grade, primarily for the food industry and surgical equipment, with molybdenum added to achieve a special corrosion-resistant structure. Due to its superior chloride corrosion resistance compared to 304, it is also used as "shipboard steel." SS316
It is commonly used in nuclear fuel reprocessing facilities. 18/10-grade stainless steel also typically meets this application level. [1] Type 321—Other properties are similar to 304, except that the addition of titanium reduces the risk of weld seam corrosion. 400 Series—Ferritic
Martensitic Stainless Steel: Type 408 - Good heat resistance, weak corrosion resistance, 11% Cr, 8% Ni. Type 409 - Cost-effective model (in the UK and US), commonly used for car exhaust systems, belongs to ferritic stainless steel (chrome steel). Type 410 - Martensitic
(High-strength Chrome Steel), good wear resistance, poor corrosion resistance. Model 416 – Added sulfur to improve the material's processing properties. Model 420 – "Cutting Tool Grade" martensitic steel, similar to early stainless steels like Bresh High Chrome Steel. Also used in surgical procedures.
Knives, can be made very shiny. Model 430—Ferritic stainless steel, decorative, e.g., for automotive accessories. Good formability, but lower temperature resistance and corrosion resistance. Model 440—High-strength tool steel, slightly higher carbon content, properly
Heat treatment results in higher yield strength, with hardness reaching 58HRC, placing it among the hard stainless steels. Common applications include "razor blades." There are three standard types: 440A, 440B, and 440C, with an additional 440F (easier to machine) available.
500 Series - Heat Resistant Chromium Alloy Steel. 600 Series - Martensitic Precipitation Hardening Stainless Steel. Model 630 - A commonly used precipitation hardening stainless steel grade, also known as 17-4; 17% Cr, 4% Ni.
