Recently, CISA (China Iron and Steel Industry Association) announced the list of Gold Cup Prize of Metallurgy Products in 2017. The cold heading steel wire rod for high-end GML40Cr、GSCM435、GSCM440Φ5.5～Φ38(mm) won this prize.
GSCM435and GSCM440 products have the advantages of uniform-chemical composition, low percentage of harmful elements,high purity, slight decarburization,Stabletensile strength, high reduction of area.After spheroidizing annealing, the products have characteristics of low crack ratio in cold heading,stable heat-treatment properties and uniform hardenability. They are applied to automobile and High-end engineering machinery. Now, they have been used successfully onBeijing Auto, Changan Automobile, Anhui Jianghuai Automobile, Weichai, etc.
GML40Cr includes GML40Cr, GML40Cr-A,G ML40Cr-B.After spheroidizing annealing,it has stable heat-treatment properties and uniform hardenability. The cold heading cracking rate is in the leading position in China, and the quality of products has been fully affirmed and recognized in every customer.It has been used on Chery, Jianghuai, Soueast, Hafei, Jinbei, Jiangling,Venucia and SAIC Motor.
There are 142 products awarded Gold Cup Prize of Metallurgy Products in metallurgical industry in 2017. The quality of these products has reached the international level ofsimilar products.
