Stainless steel pipe is a hollow long round steel with strong corrosion resistance, good mechanical properties, excellent processing performance, etc. It is widely used in the fields of petroleum, chemical industry, medical treatment, food, light industry, mechanical instrumentation, etc. The following are some common stainless steel pipe main models:
1. 304 stainless steel pipe: has good corrosion resistance, heat resistance, low temperature strength and mechanical properties, good hot processing properties such as stamping and bending, and no heat treatment hardening phenomenon. Application: tableware, cabinets, boilers, auto parts, medical equipment, building materials, food industry.
2. 316 stainless steel pipe: 316 stainless steel pipe is a pipe with chromium, nickel and molybdenum as the main alloy elements. Due to the molybdenum element, it has excellent corrosion resistance in chloride ion environments and highly corrosive chemical media, which is better than 304 stainless steel pipes. It has good mechanical properties, high tensile strength, toughness and ductility, excellent processing performance, and can be cut, bent and welded in a variety of ways. It is widely used in marine engineering, chemical industry, medical equipment and other fields, and is an ideal choice for many scenes with high requirements for corrosion resistance and material performance.
3. 310 stainless steel pipe: 310 stainless steel pipe is an austenitic stainless heat-resistant steel, the main components of which are chromium and nickel. The main feature is high temperature resistance, It is mainly used in petrochemical industry, power industry, aerospace industry, food processing industry
4. 303 stainless steel pipe: By adding a small amount of sulfur and phosphorus, it is easier to cut than 304, and its other properties are similar to those of 304 stainless steel seamless pipe.
5. 302 stainless steel pipe: 302 stainless steel rod is widely used in auto parts, aviation, aerospace hardware tools, chemical industry. Specifically as follows: handicrafts, bearings, sliding flowers, medical instruments, electrical appliances, etc. Characteristics: 302 stainless steel ball is austenitic steel, which is similar to 304, but 302 has a higher hardness, HRC≤28, and has good rust and corrosion resistance.
6. 301 stainless steel pipe: good ductility, used for forming products. It can also be quickly hardened by mechanical processing, and has good weldability. Its wear resistance and fatigue strength are better than 304 stainless steel pipes.
7. 202 stainless steel pipe: It is a chromium-nickel-manganese austenitic stainless steel with better performance than 201 stainless steel.
8. 201 stainless steel pipe: It is a chromium-nickel-manganese austenitic stainless steel with relatively low magnetism.
9. 410 stainless steel pipe: belongs to martensite (high-strength chromium steel), with good wear resistance and poor corrosion resistance.
10. 420 stainless steel pipe: "Cutting tool grade" martensitic steel, similar to Brinell high chromium steel, the earliest stainless steel. It is also used for surgical knives and can be made very bright.
11. 304L stainless steel pipe: As a low-carbon 304 steel, under normal circumstances, its corrosion resistance is similar to that of 304, but after welding or stress relief, its resistance to intergranular corrosion is excellent, and it can maintain good corrosion resistance without heat treatment.
