Standard Hardenable Martensitic Steel Round AISI P20 For Corrosion
-resistant Mould
Product Introduction
Type 420 Stainless Steel round bar is hardenable, martensitic steel that is a change of Alloy 410.
Like 410, it contains no less than 12% chromium, adequately
satisfactory to give utilization safe properties. Composite 420
have higher carbon content than Alloy 410 which is proposed to
overhaul quality and hardness traits. Martensitic stainless steels
are expected for high hardness and once in a while unique
properties are to some degree exchanged off. Consumption resistance
is lower than the normal austenitic assessments and their important
working span is obliged by their loss of adaptability at beneath
zero temperatures and loss of value by over-treating at raised
temperatures.
Grade 420 Stainless Steel is ferritic, straight chromium,
non-hardenable assessment, joining incredible disintegration
resistance and formability traits with accommodating mechanical
properties. Its ability to contradict nitric destructive strike
permits its use specifically substance applications yet auto trim
and machine sections addresses its greatest fields of utilization.
1.2083 is a martensitic stainless steel with high hardenability
(good wear resistance) and excellent resistance to cold atmospheric
corrosion and hot oxidation ( 660ºC). It also has good resistance
to chemical products.Corrosion-resistant mould steel, highest
cleanliness and good polishability, good machinability, low
distortion through- hardening steel, high hardenability, high wear
resistance
Features
Medium-carbon high-Chromium martensite stainless steel mould steel
Good mechanical properties, high hardenability, low distortion
during heat treatment
Hardness can be obtained up to 48-52HRC with proper heat treatment
in order to obtain better polishability, corrosion resistance and
wear resistance.
Pure & Precision mirror polishing
Highly quality of corrosion resistance
Convenient heat treatment for quenched&tempered steel, with out
deformed
Easy for welding
