Baojing Steel is a professional stainless steel coil manufacturer & supplier, supplying high-quality cold rolled +hot rolled austenitic stainless steel coils for industrial, commercial, architectural and engineering applications worldwide.
Austenitic stainless steel is the most widely used stainless steel family, offering an excellent combination of corrosion resistance, formability, weldability, toughness and surface quality. Our austenitic stainless steel coils are available in various grades, thicknesses, widths, surface finishes and international standards to meet different application requirements.
We supply 304 / 304L / 316 / 316L / 321 / 310S / 301 / 201 / 202 / 203...stainless steel coil, as well as other customized grades.
We provide both cold rolled stainless steel coil and hot rolled stainless steel coil.
Cold rolled austenitic stainless steel coils offer excellent dimensional accuracy, smooth surfaces and good mechanical properties.
Hot rolled stainless steel coil is mainly used for applications requiring heavier thicknesses, high strength and further processing.
