Product Introduction
Alloy 420 is a hardenable, martensitic stainless steel that is a modification of Alloy 410. Similar to 410, it contains a minimum of 12% chromium, just sufficient enough to give corrosion resistant properties. Alloy 420 has higher carbon content than Alloy 410 which is designed to optimize strength and hardness characteristics. It has good ductility it the annealed condition but is capable of being hardened up to Rockwell hardness 50 HRC, the highest hardness of the 12% chromium grades. Due to its hardening properties, Alloy 420 is not often welded, although it is possible. Martensitic stainless steels are designed for high hardness and sometimes other properties are to some degree compromised. Corrosion resistance is lower than the common austenitic grades and their useful operating range is limited by their loss of ductility at sub-zero temperatures and loss of strength by over-tempering at elevated temperatures. Its best corrosion resistance is achieved when the metal is hardened and surface ground or polished.

General Applications
2083 is in the class of stainless steel and tooling for plastic mould.Its reputation stand by the corrosive resistance properties. Rust free throughout storage period Good for mold application in high humidity, water cooling condition Suitable for any plastic mold, mold that require high corrosive such as Amino plastic, thermo plastic PVC Plastic Moreover, it can stand for abrasive and wear, so this is good for plastic thermo setting mold. Thanks to its polishing ability, it can be used for Spectacular lens, camera lens, science experimental tube, syringe.Also, good for any cutting task like knife, cutting tool, kitchen utensil, spring, seal valve or machine part for mining/wood industry.
