200 series grade BN4 cold rolled stainless steel coils 0.3-3.0mm
200 series grade BN cold rolled stainless steel coils
BN series of products, namely nickel chromium manganese nitrogen austenitic stainless steel, which is belong to nickel-saving austenitic stainless steel or economic austenitic stainless steel type. is designed by BAOSTEEL. The design concept is to add Mn N, replace partially or completely the noble metal elements of Ni, for purpose of obtain the single austenite organization,in addition to improve the processing performance, adding a certain volumn of Cu element(1~2%).
BN series have good mechanical, formability, weldability and corrosion resistance properties, can meet requirements of use of stainless steel materials in general corrosion environment (non strong acid, strong alkali environment).
At present, according to different requirements and usage ,BN series of products consists in 7 brands: namely BN4,BNDDQ,BN2,BN1D,BN1P ,BN1H AND BN1G, have successfully applied to containers, products, household appliances, building decoration and other industries.
