Classification Of Technical Standards For Stainless Steel Plates

High-strength stainless steel plate with excellent corrosion resistance, bending performance, toughness of welded parts, and stamping performance of welded parts, as well as manufacturing method thereof. Specifically, the stainless steel plate containing C: 0.02% or less, N: 0.02% or less, Cr: 11% or less than 17%, and the appropriate content of Si, Mn, P, S, Al, Ni, and 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, 0.006≤C N≤0.030 is heated to 850~1250 °C, and then carried out at 1 °C/ Heat treatment of cooling rate above s. In this way, it can become a high-strength stainless steel plate with a structure containing more than 12% martensite with a volume fraction of more than 12%, high strength of more than 730MPa, corrosion resistance and bending processability, and excellent toughness in the welding heat-affected zone. Reuse of Mo, B, etc., can significantly improve the stamping performance of welded parts.
The flame of oxygen and gas cannot cut the stainless steel plate because the stainless steel is not easily oxidized.
The 5CM thick stainless steel plate is processed with special cutting tools, such as:
(1) Laser cutting machine with a large wattage,
(2) Hydraulic saw,
(3) grinding disc,
(4) Hand saw
(5) Wire Cutting machine.

Model 301-Good ductility for molded products. It can also be quickly hardened by machining. Good weldability. The wear resistance and fatigue strength are better than those of 304 stainless steel. Type 302-Same corrosion resistance as 304, with better strength due to the relatively high carbon content. Model 303-By adding a small amount of sulfur and phosphorus, it is easier to cut than 304. Model 304-General Purpose Model; i.e. 18/8 stainless steel. The GB grade is 0Cr18Ni9. Model 309-Better temperature resistance than 304. Type 316-After 304, the second most widely used steel grade, mainly used in the food industry and surgical equipment, the addition of molybdenum element to obtain a special corrosion-resistant structure. Because it has better resistance to chloride corrosion than 304, it is also used as "marine steel". SUS316 is commonly used in nuclear fuel recovery units. Grade 18/10 stainless steel is also generally suitable for this application class. [1] Model 321-Similar to 304 except that the addition of titanium reduces the risk of corrosion in the welds of the material. 400 Series-Ferritic and Martensitic Stainless Steels Type 408-Good heat resistance, weak corrosion resistance, 11% Cr, 8% Ni. Model 409-Less expensive model (Anglo-American), commonly used as an exhaust pipe for automobiles, is a ferritic stainless steel (chromium steel). Type 410-martensitic (high-strength chromium steel) with good wear resistance and poor corrosion resistance. Model 416-Sulfur has been added to improve the addition of materials
