Exporters & Supplier of Stainless Steel 304/304l Flat Bar

 

Mahavir Metals India Exporters & Supplier of Stainless Steel 304/304L Flat Bars, Stainless steel Flat Bars 304 and stainless steel Flat Bars 304L are other names for the same metal. Type 304 stainless steel is the most versatile and commonly used stainless steel. It is still known by its previous designation 18/8, taken from the nominal composition of type 304, which is 18% chromium and 8% nickel. Type 304 stainless steel is an austenitic grade that may be deep-drawn to extreme depths. Because of this feature, 304 is the most commonly utilised grade in applications such as sinks and saucepans. The low-carbon version of 304 is 304L. It is used to increase weldability in heavy gauge components. Certain goods, including plates and pipes, may be available in "dual certified" material that meets both 304 and 304L requirements.
