Mechanical properties of 201: Tensile strength: ≥ 515 MPa Yield strength: ≥ 275 MPa Elongation: ≥ 40 Reduced area: ≥ 45
Mechanical properties of 304: Tensile strength: ≥ 515MPa Yield strength: ≥ 205MPa Elongation: ≥ 40 Reduced area: ≥ 50
The 304 stainless steel tube is a grade of stainless steel produced in accordance with American ASTM standards. 304 stainless steel tube is equivalent to China's 0Cr19Ni9 (0Cr18Ni9) stainless steel tube. 304 contains 19% chromium and contains 9% nickel.
304 stainless steel pipe is the most widely used as stainless steel, heat-resistant steel, food equipment, general chemical equipment, and atomic energy industrial equipment.
The 304 stainless steel tube is a versatile stainless steel tube that is widely used to make equipment and parts that require good overall performance (corrosion resistance and formability).
304 stainless steel pipe is the most widely used stainless steel and heat resistant steel. Used in food production equipment, Xitong chemical equipment, nuclear energy, etc.
