SS47 Studs is a metal rod or bar with threads on both sides. It also known as double-headed screws or studs, used to connect two parts together. General for mining machinery, bridges, cars, motorcycles, boiler steel structure, hanging tower, large span steel structure and large buildings.
We tend to use studs when the parts need to remove frequently, because the thread will be worn if install and remove often, then we need to change the studs.
347 stainless steel is variant of the basic austenitic 18/8 Grade 304 with added Columbium – the introduction of Columbium stabilizes the steel and eliminates carbide precipitation which subsequently causes intergranular corrosion.
The steel has excellent forming and welding qualities and excellent toughness even at cryogenic temperatures.
347 alloy applications:
Widely used in petroleum, chemical, pharmaceutical, food, machinery, aerospace, construction, military, hardware, boiler gas, plumbing devices, ships, power plants and other industries. 347 alloy added to the stability of the element niobium, especially suitable for high temperature use of welding components.
