321 Stainless Steel Square Bar
Stainless steel square bar is a kind of stainless steel products, Good corrosion resistance, heat resistance, low temperature strength and mechanical properties.
Our company provide factory competitive price.
We are willing to provide samples for testing.
Product Details
Stainless steel square bar is a solid strip of steel material,Its common material is SS304,SS304L,SS321,SS316,SS316L. And its surface has four kinds:black ,bright,polishing,hairline.
The bright surface is higher than black surface stainless steel square bar.
And because of the good corrosion resistance,heat resistance,stainless steel square bar is used in automatic machine cutting.
321 stainless steel plate is Ni-Cr-Mo austenitic stainless steel plate, its performance is very similar to 304 stainless steel plate, but because of the addition of titanium metal, it has better grain boundary corrosion resistance and high temperature strength. The formation of chromium carbide is effectively controlled by adding titanium metal.
SS321 is used for lining and conveying pipe of wear-resisting acid container and wear-resisting equipment.
| 300series :chromium nickel Austenite Stainless Steel | |
| 301 | Good ductility for molding products. It can also be quickly hardened by mechanical processing. Good weldability. The wear resistance and fatigue strength are better than 304 stainless steel |
| 302 | Corrosion resistance with 304, due to relatively high carbon and therefore better strength |
| 303 | It is easier to machined than 304 by adding a small amount of sulfur and phosphorus. |
| 304 | General model; So 18/8 stainless steel. The standard ingredient is 18 % chromium and 8 % nickel. For non magnetic stainless steel, can not be changed by heat treatment of its metallographic structure. |
| 304L | Same characteristics of 304, but low carbon so more corrosion resistance, easy heat treatment, but poor mechanical suitable for welding and not easy heat treatment products. |
| 304 N | Same characteristics of 304,is a kind of stainless steel containing nitrogen, nitrogen is to improve the strength of steel. |
| 309 | Compared with 304 has better temperature resistance, temperature resistance up to 980℃ |
| 309 S | With a lot of chromium, nickel, heat resistance, oxidation resistance, such as: heat exchanger, boiler components, jet engine |
| 310 | High temperature oxidation resistance, the highest operating temperature of 1200℃ |
| 316 | Addition of molybdenum gives it a special structure that is resistant to corrosion. It is also used as "Marine steel" because of its better resistance to chloride corrosion than 304. SS316 is usually used in nuclear fuel reprocessing units. Grade 18/10 stainless steel is also usually qualified for this application class |
| 316L | Low carbon, more corrosion resistance, easy heat treatment |
| 321 | Addition of Titanium,lower the risk of weld corrosion |
| 347 | Addition of Niobium for stabilizing, used for welding aerospace parts and chemical equipment |
