Product Description

2520 sanitary grade Seamless Stainless Steel Pipe polished stainless steel tube


1. Type of 2520 stainless steel grade


2520 stainless steel is an abbreviation for China's stainless steel standard.

2520 Chinese Standard

Old grade: 0Cr25Ni20 (GB/T3280-1992)

New grade: 06Cr25Ni20 (GB/T20878-2007)

China Uniform Digital Code: S31008 (GB/T20878-2007)


2. The main properties of 2520 stainless steel


Due to high content of nickel (Ni) and chromium (Cr), it has good oxidation resistance, corrosion resistance, acid and alkali resistance and high temperature resistance. High temperature resistant steel tubes are specially used for the manufacture of electric heating tubes, etc., and carbon is added to austenitic stainless steel. After the content, the strength is improved by the solid solution strengthening effect. The chemical composition of the austenitic stainless steel is based on chromium, nickel and other elements such as molybdenum, tungsten, niobium and titanium. Since the structure is a face-centered cubic structure, Thus there is high strength and creep strength at high temperatures. 2520 stainless steel material has 2520 stainless steel plate, 2520 stainless steel rod, 2520 stainless steel tube, 2520 stainless steel angle steel, 2520 stainless steel flat steel, round steel, stainless steel plate, stainless steel rod, stainless steel tube, which can work at a high temperature of 1250 degrees for a long time.


3. Physicochemical properties and mechanical properties of 2520 stainless steel


1. Physical and chemical properties

It has high high temperature strength and oxidation resistance, and is sensitive to sulfur-containing atmosphere. It has a brittle tendency of precipitated phase at 600-800 °C, and is suitable for making various furnace components subjected to stress.

2, mechanical properties

Tensile strength σb (MPa): ≥ 590 Conditional yield strength σ0.2 (MPa): ≥ 295 elongation δ 5 (%): ≥ 35 section shrinkage ψ (%): ≥ 50 hardness: ≤ 187H

Stainless Steel Pipe/Tube.
Stainless steel pipe is an economical cross-section steel and an important product in the steel industry. It can be widely used in life decoration and industry. Many people on the market use it to make stair railings, window guards, railings, furniture, etc. Two common materials are 201 and 304.
Stainless steel pipe is a hollow long round steel, which is widely used in petroleum, chemical, medical, food, light industry,
mechanical instrumentation and other industrial pipelines and mechanical structural parts. In addition, when the bending and torsion strength are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures. Also often used as furniture and kitchen utensils.
