Njabulo Stainless is a well-known manufacturer and supplier of high-quality stainless steel products in Cape Town, South Africa. The company specializes in Stainless Steel 347H Bars with a promise of superior durability, corrosion resistance, and precision engineering. With a focus on innovation and customer satisfaction, Njabulo Stainless caters to diverse industries such as construction, automotive, and petrochemicals. Stainless Steel 347H Bars of these companies are valued for high temperature strength and weldability, so these bars have become very popular all over the world for challenging applications.
These stainless steel 347H bars are made of high-carbon austenitic stainless steel, having high corrosion resistance properties at high temperatures. They consist of 17-19% chromium, 9-13% nickel and 0.04-0.10% carbon along with other constituents including columbium/tantalum. These compositions help stabilize these alloys and resist the precipitation of carbides; therefore, these materials are widely used in chemical, manufacturing and petrochemical industries where there are hot and wet conditions.
