Description / Abstract:
Purpose
The purpose of this specification is to establish requirements
of a grinding method and to provide grinding parameters that will
eliminate or minimize overheating, cracking, high residual tensile
stresses, and/or other metallurgical changes that decrease
structural integrity of steel parts or chrome plated steel parts
(See 8.2). This standard establishes requirements for low stress
grinding of martensitic high strength steel heat-treated to 180 ksi
(1241 MPa) minimum ultimate tensile strength (UTS) and above, and
requirements for low stress grinding of chromium plating applied to
such high strength steel.
Application
This process has been used typically to grind chrome plating on
high strength steel and high strength steel parts heat treated to
180 ksi (1241 MPa) ultimate tensile strength and above for
applications requiring wear, heat, and corrosion resistance or
dimensional restoration, such as aircraft landing gear and
hydraulic actuator components. However, usage is not limited to
such applications (See 8.3).
Safety – Hazardous Materials
While the materials, methods, applications, and processes
described or referenced in this specification may involve the use
of hazardous materials, this specification does not address the
hazards that may be involved in such use. It is the sole
responsibility of the user to ensure familiarity with the safe and
proper use of any hazardous materials and to take necessary
precautionary measures to ensure the health and safety of all
personnel involved.
