GB/T 5953.2-2009Steel wire for cold heading and cold forging -- Part 2: Not intended for heat treatment (English PDF)

Foreword

GB/T 5953 "cold heading wire" is divided into three parts.

--- Part 1. heat-type cold heading steel wire;

--- Part 2. Non-heat-type cold heading steel wire;

--- Part 3. non-quenched cold heading steel wire type.

This section GB/T 25953 Part, modifications using JISG3507-2:2005 "Carbon steel cold upsetting" (in English).

According to this section JISG3507-2:2005 redrafted. For comparison, in information listed in Appendix A of this section shall Differences technical reasons and the list of 2005 terms. money and JISG3507-2.

This portion JISG3507-2. Compared to 2005, the main technical differences are as follows.

--- Increase "Classification and designation";

--- Increased the order content;

--- Grade and chemical composition is different;

--- Increase forging test requirements;

--- Mechanical specifications by wire segments;

--- Increase "carburant" Check project agreement.

1 Part, and Part common instead of GB/T 5953-1999 "cold heading wire."

Section compared with GB/T 5953-1999 The main changes are as follows.

--- Modify the delivery status;

--- Increased the order content;

--- Expanding the wire diameter range, expanded from (1.00 ~ 16.00) mm to (1.00 ~ 45.00) mm;

--- Improving the dimensional accuracy and flatness;

--- Improving the heavy plate;

--- Canceled tag example;

--- Tightened the decarburization requirements;

--- Added "carburizing" requirement.
