Stainless steel sheet is a metal material widely used in several industries, including construction, automotive, medical equipment and kitchenware. Due to its excellent corrosion resistance, heat resistance and strength, stainless steel sheet is the material of choice for many engineering projects. At the same time, stainless steel materials have an easy-to-clean surface, can be recycled and reused, and have an irreplaceable role in the food and medical industry.
There are ten common surface types, they are No. 1, 2B, BA, No. 4, HL, 6K, ordinary 8K, fine grinding 8K, 8K+HL, sandblasting. Different surface states are suitable for different scenarios, Jiangsu Tisco Tianguan Metal Products Co., Ltd. introduces you the different applications and differences of these different surface states, so that you can use them as a reference when purchasing and using stainless steel materials.
