VANDAN ALLOYS is a known trader and offers a wide range of Duplex Stainless Steel Screws, which has good weldability in thick plates and good low temperature toughness. Although it has good high temperature oxidation resistance, our Duplex Steel Screws suffers from embrittlement if held for even short times at temperatures above 300 Degree C. Solution treatment or annealing can be done by rapid cooling after heating to around 1100 Degree C, where these Duplex Steel Hex Head Screws cannot be hardened by heat treatment and can however be work hardened. Anneal Heat of our Duplex Steel Socket Head Cap Screws is done up to 1020 Degree C – 1120 Degree C ensuring sufficient time is allowed for the centre to achieve furnace temperature and hold for a time commensurate with the ruling section, followed by water quenching. These Duplex Steel Socket Set Screws is difficult to form due to its high strength and work hardening rate, where for maximum corrosion resistance, that cleanliness must be maintained or restored after handling or fabrication.
