Description
Stainless steel is notable for its corrosion resistance, and it is widely used for decoration,food handling and cutlery among many other applications. Stainless steel does not readily corrode, rust or stain with water as ordinary steel does. There are various grades and surface finishes of stainless steel to suit the environment the alloy must endure.
Application
Stainless steel has good processing performance and weld ability. It is suitable for food processing, storage and transportation, and it can be applied to water heaters, boilers, bathtubs, auto parts (windshield wipers, muffler and molded products), medical equipment, building materials, chemical, food industry, agriculture, marine components, and so on.

Quality Assurance Commitment
We strictly in accordance with the ISO 9001 quality management We have established the international advanced quality management system,every link from raw material to final product we have strict quality test;We resolutely put an end to unqualified products flowing into the market. At the same time, we will provide necessary follow-up service assurance.
1.Raw material inspection: dimension and tolerance check, appearance quality check, mechanical properties testing, weight check and raw materials quality assurance certificate check
2.Semi-finished goods inspection: physical and chemical inspection, leakage magnetism and ultrasonic inspection
3.Finished goods inspection: dimension and tolerance, appearance quality check and mechanical properties testing
