H13 tool steel is the most widely used and most representative hot work die steel. Its main characteristics are:(1) A573 Gr 58 CS steel carbon plate has high hardenability and high toughness;(2) Excellent thermal crack resistance, water cooling can be used in the work place;(3) With moderate wear resistance, carburizing or nitriding processes can also be used to increase the surface hardness, but the thermal crack resistance should be slightly reduced.
40B steel plate is alloy structural steel plate formed by adding boron to the carbon structural steel with a carbon content of 0.40%. A573 Gr 58 CS steel carbon plate, 40B steel plate has high hardness, toughness and hardenability, and has good comprehensive mechanical properties after quenching and tempering, which can be used instead of 40Cr steel. 40B steel plate chemical elements: C: 0.37-0.44, Si: 0.17-0.37, Mn: 0.60-0.90, B: 0.0005-0.0035. 40B steel plate is used to manufacture parts with larger section and higher performance requirements.
The purpose of complete annealing of A573 Gr 58 CS steel carbon plate, wear-resistant plate is to improve the bad structure, such as coarse grain, widmanstatten structure (coarse ferrite with directional growth along with coarse grain) or banded structure caused by high temperature during hot forging, hot rolling, welding or casting of steel plate, so as to refine grain, improve mechanical properties, and reduce stress and hardness.
The chemical composition difference between A573 Gr 58 CS steel carbon plate, 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 A573 Gr 58 CS steel carbon plate, 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.
