STECO accept any customized cobalt-based alloy.
Band saws and circular saws used in woodworking are often welded with alloy serrations to save costs and extend service life. Commonly used saw tips include cemented carbide, STP alloy and high-speed steel. STP saw tips is suitable for cutting some abrasive or acidic woods, such as red cedar.
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.
Stellite alloys are widely used in oil and gas industries, such as valve ball seats and valve cages in underground rod-type oil pumps, and stators, rotors, bushings, etc. in exploration equipment.
We aim to provide the best solution for our customers in the high thermal, wear and corrosion area.
