Preface: Instead of this standard GB/T3207-1988 "the silver steel". Compared this standard with GB/T3207-1988, the main technical changes are as follows: - silver steel diameter from 0.6 MM to 80 MM to 1.0 MM to 180 MM; - increase bohler and stripping materials, the definition of repairing Change the definition of polishing material; - to cancel the original standard grinding to pull in the delivery status; - increases the reference area larger than 80 mm in diameter and reference weight; - changed the diameter deviation corresponding to the diameter of the allowed range, the diameter of 0.6 MM to 1.0 MM and > into 1.0 MM ~ 1.0 MM diameter 3.0 MM or less, or more than 50 MM specification range points three specifications: > 50 MM to 80 MM, 80 MM to 120 MM, > > 120 MM to 180 MM; - increase the diameter of the silver steel level of allowable deviation, from 7 to 11 for 6 ~ 13 level; - modify bohler long Degree, enhance the length allowed deviation; - modify bohler appearance requirements, by not greater than 10 MM diameter bohler allowed in the state of the volume of delivery, modified to have by mutual agreement, silver steel coil can delivery status; - amend the bending to straightness; - modify straightness, cancel the total curvature index O; - modify bohler end appearance requirements; - cancel tag sample; - increase bohler process performance requirements; - increase the roughness requirements; - modify packaging requirements, increase the specific requirements of the transportation and storage. This standard put forward by the China iron and steel association. This standard by the national steel standardization technology The committee to review. This standard drafting unit: the northeast special steel group co., LTD and information standards institute of metallurgy industry. Main drafter of this standard: true yun, willow, Wang Lingjun, Dai Shifeng, Zhou Minjun, mei-jian xu. This standard replaced all previous releases as: GB/T3207-1982, G B/T3207-1988  
Description:This standard instead of gb/t 3207-1988 "the silver steel".
this standard stimulates the bohler terms and definitions, classification code, size, shape, weight and allowable deviation, technical requirements, test methods, inspection rule, mark and quality certificate, packing, transportation and storage requirements.
this standard applies to have high requirements on surface quality of the peeling, grinding and polishing of round steel.
this standard and gb/t 32 07-1988, compared to the main technical changes are as follows:
- silver steel diameter range from 0.6 mm to 80 mm to 0.6 mm to 180 mm;
- increase bohler and skinning material definition, modify the definition of polishing material;
- cancel "grinding" in the original standard delivery state;
- increases the reference area larger than 80 mm in diameter and reference weight;
-- changed the diameter deviation corresponding to the diameter of the allowed range, the diameter of 0.6 mm and > 1.0 mm ~ 3.0 mm into a diameter of 3.0 mm or less, more than 50 mm specification range points three specifications: > 50 mm ~ 80 mm, 80 mm to 120 mm >, > 120 mm to 180 mm;
- to increase the diameter of the silver steel level of allowable deviation, from 7 to 11 for 6 ~ 13 level;
- modify bohler length, tightened length allowed deviation;
- modified bohler appearance requirements, by not greater than 10 mm diameter bohler allowed in the state of the volume of delivery, modified to have by mutual agreement, silver steel coil can delivery status;
--, amend the bending to straightness;
- modified straightness, cancel the total curvature index requirements;
- modified bohler end appearance requirements ;
- cancel tag sample;
- increase bohler process performance requirements;
- increasing roughness requirement;
- modify packaging requirements, increase the specific requirements of the transportation and storage.
