Quality S550 steel shot cheap price

The chemical composition difference between S550 steel shot, Q235B and 20# steel is as follows: The chemical composition of 20# steel: C: 0.17-0.23%, Si: 0.17-0.37%, Mn: 0.35-0.65%, Cr: ≤ 0.25%, Ni: ≤ 0.30%, Cu: ≤ 0.25%. Chemical composition of Q235B steel: C: ≤ 0.20%, Si: ≤ 0.35%, Mn: ≤ 1.40%, P: ≤ 0.045%, S: ≤ 0.045%. The difference of mechanical properties between S550 steel shot, Q235B and 20# steel is as follows: The mechanical properties of 20# steel: tensile strength 410 MPa; yield strength 245 MPa; elongation after fracture: 25; reduction of area: 55; no impact. Q235B steel mechanical properties: tensile strength 370-500 Mpa; yield strength: ≥ 235 Mpa; elongation after fracture: 25; impact absorption energy: 27J.

The head of the National Development and Reform Commission, He Lifeng, chaired a special meeting of the Office of the Leading Group for the Development of the Yangtze River Economic Belt. The meeting emphasized that the Yangtze River Economic Belt is the center of gravity and vitality of China's economy, and is of great significance to the overall economic and social development of the country. At present, we must focus on four tasks. The first is to make every effort to resume work and achieve production. The second is to make every effort to promote ecological environmental protection and restoration. The third is to strengthen project reserve work. The fourth is to improve the planning guarantee system.
