Delivery Condition
| Designation | Symbol | Description |
| Cold finished (hard) | BK | SCM415 SCM420 SCM435 SCM440 JIS alloy steel do not undergo heat treatment following the final cold forming and, thus, have a rather high resistance to deformation. |
| Cold finished (soft) | BKW | The final heat treatment is followed by cold drawing involving limited deformation. Appropriate further processing allows a certain degree of cold forming (e.g. bending, expanding). |
| Cold finished and stress-relieved | BKS | Heat treatment is applied following the last cold forming process. Subject to appropriate processing conditions, the increase in the residual stresses involved enables both forming and machining to a certain degree. |
| Annealed | GBK | The last cold forming process is followed by annealing in a controlled atmosphere. |
| Normalized | NBK | The last cold forming process is followed by annealing above the upper transformation point in a controlled atmosphere. |
FAQ
What is SCM440 steel equivalent to?
SCM440 steel is equivalent to 4140 steel, a chromium-molybdenum alloy steel.
What is the hardness HRC of SCM440?
The hardness of SCM440 is usually around HRC 40-44.
What is SCM steel?
SCM steel stands for Super Carbon Manganese steel. It is a type of medium-carbon steel that has enhanced strength and is resistant to abrasion. SCM steel is typically used to make items like cutting tools, gears, and components that require high hardness and strength.
What is the price of SCM440?
The price of SCM440 depends on a variety of factors including the current market price, the size and quantity purchased, and any additional services such as cutting, machining, or special treatments. Generally speaking,
