45# seamless steel pipe (No.45 seamless steel pipe) is Chinese high-quality carbon structural steel, which is called S45C in Japanese standard, AISI 1045 in American standard, and C45 in German standard. The difference between 45# seamless steel pipe and 20# seamless steel pipe is that its hardness is obviously higher than that of 20# seamless steel pipe. The tempering brittleness of S420MC alloy steel sheet, 45# seamless steel pipe is high. After quenching and tempering, 45# seamless steel pipe has good mechanical properties. If the wear resistance is considered, heat treatment is required.

Bridge steel plates are thick steel plates made of carbon steel and low-alloy steel for bridge construction. The main applications of bridge steel plates are to build railway bridges, highway bridges, and sea-crossing bridges. The bridge steel plates are required to have high strength, durability and bear the load and impact of rolling stock. Bridge steel plates have good water resistance, low thermal conductivity, flat and lubricated surface. The main grades of bridge steel plates are A709 grade 50, A588 grade B, S420MC alloy steel sheet and so on.

What is S420MC alloy steel sheet, boiler steel consumption rate? The cost of the boiler, to a large extent, depends on the steel consumption of the boiler. The so-called boiler steel consumption rate refers to the tons of boiler steel used per 1t / h evaporation capacity of the boiler, also known as the boiler steel consumption per unit evaporation. The boiler steel consumption rate of boilers with different parameters, capacities and structures is different.

The chemical composition difference between S420MC alloy steel sheet, 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 S420MC alloy steel sheet, 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.
