420 Grade Stainless Steel Sheet
The top supplying country or region is china which supply 100 of stainless steel sheet grade 420 respectively.
420 grade stainless steel sheet. Also referred to as a4 in accordance with international organization for standardization iso 3506. Thickness tolerance specified width. 420 stainless steel is martensitic stainless steel that provides corrosion resistance similar to type 410 plus increased strength and hardness. It offers good ductility in its annealed state and excellent corrosion resistance properties when the metal is polished surface grounded or hardened.
Ak steel type 420 is a martensitic stainless steel that provides corrosion resistance similar to type 410 plus increased strength and hardness. North america s largest supplier of 420 stainless steel metric sheets. Like any other stainless steel grade 420 can also be hardened through heat treatment. Grade 420 stainless steel is a high carbon steel with a minimum chromium content of 12.
General properties alloy 420 is a hardenable martensitic stainless steel that is a modification of alloy 410. 304 316 409 420 430 cold rolled stainless sheet. 420 stainless steel blade grade martensitic steel the earliest stainless steel similar to brinell high chromium steel. Maximum corrosion resistance is attained only in the fully hardened or fully hardened and stress relieved condition.
Similar to 410 it contains a minimum of 12 chromium just sufficient enough to give corrosion resistant properties. Equal to less than 1000 1000 thru 1300 1300 thru. It is also used for surgical cutting tools which can be very bright. Rolex is an exception in that they use type 904l.
It is magnetic in both the annealed and hardened conditions. The processing properties of the material are improved by adding sulfur. 18 10 stainless often corresponds to this grade. Basic martensitic grade containing the lowest alloy content of the three basic stainless steels 304 430 and 410.
Related grades to 420 are high carbon high hardness martensitic stainless steels such as the 440 series see the atlas datasheet on this series of grades and also variations to 420 containing molybdenum for increased corrosion resistance and mechanical properties sulphur for increased machinability or vanadium for higher hardness. A wide variety of stainless steel sheet grade 420 options are available to you there are 32 stainless steel sheet grade 420 suppliers mainly located in asia. Low cost general purpose heat treatable stainless steel. Most watches that are made of stainless steel are made of this grade.
When fully hardened it is the hardest of this family of stainless steels.
