TP347/TP347H/1.4961/S34709 Seamless Stainless Steel Pipe for Use

Despite its lean nickel content, 253 MA offers an outstanding combination of creep strength and high resistance to oxidation, sulphidation and erosion/abrasion at extremely high temperatures. This makes the alloy more economical than most heat resistant alloys.

The high heat resistant properties of 253 MA are obtained by the tight control of micro alloy additions. Whilst the benefit of creep rupture strength is down to the combination of nitrogen, carbon and cerium, its superior oxidation resistance is a result of the combination of cerium and silicon.

Its strength at these temperatures is higher than that of alternatives such as Grade 310.
