12Cr2Mo1R(H) material is a hydrogen container plate, "R" represents the first capital letter of the container plate, and H is a hydrogen container. 12 is a chemical element,

What is the XAR400 steel hardness

XAR400 steel hardness (in room temperature): 360 to 440HB
The Brinell hardness is determined according to the ISO6506 standard. Hardness should be measured approximately 1 mm below the surface.

What is the quenching temperature of 45# steel?

45# steel is a medium carbon structural steel with good hot and cold workability, good mechanical properties, low price and wide source. Its biggest weakness is the low hardenability, large cross-section size and relatively high requirements of the workpi

What is the XAR500 steel?

XAR500 steel is a special structural steel plate, which has extremely high wear resistance. Generally speaking, the higher the hardness, the higher the wear resistance of the corresponding steel plate. Excellent martensite or martensite-bainite structure.

What is the delivery condition of Q345D alloy
