15CrMo steel is a heat-resistant steel with pearlite structure, which has high thermal strength (δb≥440MPa) and oxidation resistance at high temperatur
For the rolling of 15CrMo steel plate, the following standard requirements need to be met:
(1) Deviation requirements for thickness, width and length
The thickn
1. Cracks appear on the surface of 15CrMo steel after carburizing
Reason:
a.The concentration of surface penetration layer for 15CrMo steel is too high.
b.15CrM
The alloy layer of the NM500 steel has high wear resistance, and the service life of the parts after surfacing is relatively long, which will increase by about
·Cutting. Use plasma cutting, carbon arc cutting and grinding wheel saw to cut large-area composite NM500 wear-resistant steel plates into required shape
Impact resistance. The impact resistance of the NM500 wear-resistant plate is very good. In the process of conveying materials, even if there is a very high dro
Quenching can improve the plasticity and toughness of 15CrMo steel and reduce its brittleness, but it often inevitably reduces the strength and hardness of 15Cr
15CrMo steel belongs to pearlitic heat-resistant steel. It is mainly composed of chromium and molybdenum alloying elements. The alloying element chromium can fo
Carburizing is a heat treatment process in which steel is placed in a medium with sufficient carbon potential and heated to an austenite state and kept warm to
Steel plate A285 is a carbon steel plate that is primarily used in low to intermediate tensile strength pressure vessel applications. A285 is known for its good
A285 grade C materi is a carbon steel plate material commonly used in pressure vessel applications. It offers high strength properties at a relatively low cost,
40Cr steel is a high-carbon chromium bearing steel, commonly used in the manufacture of mechanical parts and automotive engine parts, etc. To weld 40Cr steel, t
The weldability of 40Cr alloy steel is poor, and it is not easy to solder at room temperature. Stress annealing should be done immediately after welding of 40Cr
