Product Code:SAE AMS2759/7
Title:Carburizing and Heat Treatment of Carburizing Grade Steel Parts
Issuing Committee:Ams E Carbon And Low Alloy Steels Committee
Scope: This specification, in conjunction with the general requirements for steel heat treatment covered in AMS2759, establishes the requirements and procedures for three classes of gas, vacuum, liquid, and low pressure (LPC) carburizing and related heat treatment of parts fabricated from carburizing grade steels. It does not cover pack carburizing.
Rationale: This specification, in conjunction with the general requirements for steel heat treatment covered in AMS2759, establishes the requirements and procedures for three classes of gas, vacuum, liquid, and low pressure (LPC) carburizing and related heat treatment of parts fabricated from carburizing grade steels. It does not cover pack carburizing.【英文标准名称】:Informationtechnology-Securitytechniques-Digitalsignatureswithappendix-Part3:Certificate-basedmechanisms
