Product Description

Material Summary

The "H" in 347H stands for "high carbon" content. This variety of stainless steel has higher amounts of carbon than standard 347 stainless steel, with increased tensile strength and creep resistance at elevated temperatures. Due to its higher carbon content, this type of stainless steel provides better stress rupture properties than the standard version. It also offers excellent resistance to oxidation in intermittent service up to 1600F and continuous service up to 1700 degrees F.

Packaging & Shipping

1.generally export packing

   -packed by knitting strips in bundles

2.It is suggested that the pipes OD under 25MM or Less than container shipment are packed by plywood cases, which can protect pipes better.
