Valve Industry

Valves are indispensable control components in fluid delivery systems. Depending on the use environment and the contact medium, some parts of the valve such as bushings, valve seats, valve cores and sealing rings all require special materials for customized production. STP alloy valve fittings are used in extreme environments to ensure long-term stable use.

Steel Industry

Hot dip galvanizing is a form of galvanizing, a process of applying zinc to steel. In the process of galvanizing, some equipment parts of the galvanizing line need to work in high-temperature zinc solution or zinc-aluminum solution for a long time, so a material that can have high temperature resistance, corrosion resistance and wear resistance at the same time is required. STP alloy perfectly solves this problem.
