รายละเอียดเอกสาร

This specification covers carbon steel castings for general applications that require up to 485 MPa [70 ksi] minimum tensile strength. Note 1—The grades covered by this specification represent materials that are suitable for assembly with other steel castings or wrought steel parts by fusion welding. It is not intended to imply that all these grades possess the same degree of weldability or that the same welding techniques can be used on all castings. It is the responsibility of the purchaser to establish for himself a suitable welding technique.
