PRODUCT DETAILS
Product Introduction
ASTM A240 Type 420 contains increased carbon to improve mechanical properties. Typical applications include surgical instruments. SS 420 Plate is a hardenable, martensitic stainless steel that is a modification of SS 410 Plate.
Similar to SS 410 Plate, it contains a minimum of 12% chromium, just sufficient enough to give corrosion resistant properties. Available in different variations of carbon content 420 stainless steel plate is suitable for heat treatment. Stainless Steel 420 Plate has a 13% chromium content which gives the specification a level of corrosion resistance properties. British standard grades available are 420S29, 420S37, 420S45 Plate.
ASTM A240 Type 420 Applications:
Alloy 420 is used for a variety of applications where good corrosion and outstanding hardness is necessary. It is not suitable where temperatures exceeding 800°F (427°C) due to quick hardening and loss of corrosion resistance.
