Commodity name: Stainless Steel 410

Stainless steel 410 is the basic, general purpose martensitic stainless steel that is used for highly stressed parts and provides good corrosion resistance plus high strength and hardness.

Product Introduction

Stainless steel 410 is the basic, general purpose martensitic stainless steel that is used for highly stressed parts and provides good corrosion resistance plus high strength and hardness. 410 stainless steel contains a minimum of 11.5% chromium which is just sufficient enough to demonstrate corrosion resistance properties in mild atmospheres, steam, and many mild chemical environments.

It is a general purpose grade that is often supplied in the hardened but still machineable condition for applications where high strength and moderate heat and corrosion resistance are required. Alloy 410 displays maximum corrosion resistance when it’s been hardened, tempered, and then polished.

Applications

Grade 410 stainless steels find applications in the following:

Bolts, screws, bushings and nuts
Petroleum fractionating structures
Shafts, pumps and valves
Mine ladder rungs
Gas turbines

# Tempering of grade 410 steels should be avoided at temperatures of 425-600 °C, owing to associated low impact resistance.

Possible Alternative Grades

Grade	Reasons for choosing the grade
416	High machinability is required, and the lower corrosion resistance of 416 is acceptable.
420	A higher hardened strength or hardness than can be obtained from 410 is needed.
440C	A higher hardened strength or hardness than can be obtained even from 420 is needed.
