The performance and application of stainless steel pipes of different materials.

304 stainless steel pipe: Good corrosion resistance, heat resistance, low temperature strength and mechanical characteristics. Good performance of stamping, bending and other thermal processing, no heat treatment hardening phenomenon. Usage: tableware, cabinets, boilers, auto parts, medical appliances, building materials, food industry.

310 stainless steel pipe’s main characteristics : With high temperature resistance,it is generally used in the boiler and automobile exhaust pipe.Other performance is common.

303 stainless steel pipe: By adding a small amount of sulfur, phosphorus to make it easier to cut than 304.Other properties are similar to the 304 stainless steel seamless pipe.

302 stainless steel pipe: 302 stainless steel rod is widely used in auto parts,aviation, aerospace, hardware tools,chemical industry.Details are as follows: handicrafts, bearings,slides,medical instruments,electrical appliances,etc.Characteristics:302 stainless steel ball belongs to austenitic steel,which is close to 304,but the hardness of 302 is higher with HRC less than or equal to 28.It has good rust prevention and corrosion resistance.

301 Stainless steel pipe: Good ductibility for molding products.It can also be quickly hardened by machining with good weldability.Abrasion resistance and anti-fatigue strength are better than 304 stainless steel pipe.

202 stainless steel pipe: It belongs to chromium-nickel-manganese austenitic stainless steel.The performance is better than 201 stainless steel.

201 stainless steel pipe: It belongs to the chromium-nickel-manganese austenitic stainless steel.The magnetism is relatively low.

410 stainless steel pipe: It belongs to martensite (high strength chromium steel) with good abrasion resistance and poor corrosion resistance.

420 stainless steel pipe: “blade grade”martensitic steel,similar to brearley high chromium steel,the earliest stainless steel.It is also used in surgery,which can be made with great shine.

304L stainless steel pipe: As low carbon 304 steel, the corrosion resistance is similar to 304 steel under general condition.After welding or after stress elimination,it’s corrosion resistance is excellent. In case of no heat treatment,it can also maintain good corrosion resistance.

310 stainless steel pipe:It has high temperature resistance and is used in boiler and automobile exhaust pipe.Other performance is general.

1. Ferriite stainless steel contains 12% to 30% chromium.Its corrosion resistance, toughness and weldability improve with the increase of chromium content.Chloride stress and corrosion resistance is better than other kinds of stainless steel.

2. Austenitic stainless steel contains chromium which is more than 18%. It also contains about 8% nickel and a small amount of molybdenum, titanium, nitrogen and other elements. With good comprehensive performance, it can be resistant to a variety of media corrosion.

3. Austenite-ferric body duplex stainless steel has the advantages of austenite and ferric body stainless steel with good superplasticity.

4. Martensite stainless steel has high strength, but poor plasticity and weldability.
