Product information
The tests which are performed on these SS 347H Seamless Pipes are destructive test, visual test, chemical test, raw material test, flattening test, flaring test, and many other tests. These pipes are packed in wooden boxes, plastic bags, and steel strips bundles or as required by the costumers and the end of these pipes are covered with plastic caps.
And the delivery conditions of these SS 347 Seamless Pipes are annealed and pickled, polished and cold draw. And these pipes are highly corrosive resistant and can withstand high temperature, shock, and vibrations effectively. And the other advantages of these pipes are they have high strength and hardness, these pipes have good density, high melting point and have good tensile and yield strength and elongation. The chemicals present in the alloy of these SS 347H Seamless Pipes are carbon, magnesium, silicon, sulfur, phosphorous, chromium, nickel, iron-cobalt, etc.
