High strength SUS420j1 martensitic Cold Rolled Steel Strip for mold development

Wuxi Shuangyong Precision Stainless Steel Strip Co., Ltd.

Wuxi Shuangyong Precision Stainless Steel Belt Co., Ltd. was established in 2009 and is located in Luoshe Town, Huishan District, Wuxi City, adjacent to Shanghai-Chengdu Expressway and Shanghai-Wuhan Expressway, with convenient transportation.

The company is the earliest domestic manufacturer of high-end precision super-hard stainless steel, and it also deals in various middle- and high-end precision carbon steels, precision iron-nickel alloys, etc. In 2014, the company successfully passed the ISO9000 quality system certification.

After more than ten years of hard work, the company has accumulated rich experience in the field of precision steel belts, and the developed product technology is mature, which can realize the import substitution of similar products in the domestic market. In response to the special needs of customers, the company can customize special materials for them and provide relevant professional opinions for customer product development to balance product performance, cost, and supply chain reliability.

The main product features of the company are as follows:

Super-hard (SH) series stainless steel strips are made of TISCO's SUS301 cold-rolled strip material. The thickness of the product is 0.06mm-1.0mm, the width is 9mm-400mm, and the hardness is HV490-600. The product has the characteristics of large force value, stable force value, and long life. It is widely used in elastic components such as constant force springs, constant force coil springs, curtain tension springs, and electrical shrapnel.

Electronic series stainless steel strips are made of raw materials such as TISCO, Zhangpu SUS301, SUS316L, SUS304LL and other cold-rolled strips. The thickness of the product is 0.06mm-0.8mm, and the hardness is HV180-HV490. Mainly used for inner frames, brackets, back clips, etc. of consumer electronic products such as mobile phones, tablet computers, and notebook computers.

The electronic series of deep drawing carbon steel strips SPCC/SPCE/SPCG/DC06 are made of Shougang and Baosteel carbon steel raw materials. The product thickness is 0.05mm-1.06mm, the hardness is HV80-200, and the width is 10mm-600mm. Mainly used for vibration motors of consumer electronic products, housings of acoustic and optical components, signal shields, internal brackets, back covers of mobile phones, and power battery plates, etc.

The company is equipped with 5 sets of precision cold rolling units, continuous annealing furnace unit, recoiling unit, three precision shearing units, arc edge scraping unit, leveling unit, and cleaning unit. A complete set of testing equipment includes Vickers/Rockwell hardness tester, surface roughness tester, tensile strength tester, etc., to ensure the quality requirements of customers.
