Hot Rolled Pre-hardened Martensitic Stainless Steel Flat Bar S136H
6-150mm Thickness
Product Introduction
2083 is a tool steel in the group of plastic mold and stainless in
matesitic (AISI420)So, it can stand for corrosive and can be quench
to enhance it's strength together with corrosive resistance
properties.Hardness can reach up to 56 HrC , this also benefit to
polishing properties and can do texturing.Suitable for plastic mold
that need corrosive resistance such as amino plastic,thermoplastic
which has severe decompose of acitic acid as well as PVC plastic
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. Ruler and Slider calipers
