|Usage||adapted for all kinds of 8.8 intension standard-part and nonstandard -part,|
Characteristics:adapted for all kinds of 8.8 intension standard-part and nonstandard -part. Use of Products:Steel 40ACR,are the common using steels produced the Fasteners of low intension and big deformation and the nonstandard-part. The productions have advantages of steady composition, low harmful element, high pure steel and small surface defect. Using them, it is unnecessary to heat treatment and the rate craze of cold forging is low. They are used in the industry of family electricity, traffic, mechanism and transport.
