What type of material is 431?

This heat treatable martensitic, nickel-bearing grade has the best corrosion resistance properties of all the martensitic grades. It has excellent tensile and torque strength, and good toughness, making it ideally suited to shafting and bolt applications. It can be hardened to approximately 40HRC. Because of its high yield strength, this grade is not readily cold worked and is therefore not recommended for use in operations such as cold heading, bending, deep drawing or spinning.

Martensitic stainless steels are optimised for high hardness, and other properties are to some degree compromised. Fabrication must be by methods that allow for poor weldability and usually also allow for a final harden and temper heat treatment. Corrosion resistance is lower than the common austenitic grades, and their useful operating temperature range is limited by their loss of ductility at sub-zero temperatures and loss of strength by over-tempering at elevated temperatures.

SS431 is frequently stocked and supplied in “Condition T”, with specified tensile strength of 850 – 1000MPa.

* Annealed tensile properties are typical for Condition A of ASTM A276; annealed hardness is the specified maximum. SS431 is only rarely stocked in annealed Condition A.

# Due to associated low impact resistance this steel should not be tempered in the range 425-600°C

These comparisons are approximate only. The list is intended as a comparison of functionally similar materials not as a schedule of contractual equivalents. If exact equivalents are needed original specifications must be consulted.

431 stainless steel nearest possible Grades

Grade

Why it might be chosen instead of 431

SS410

Only a lower hardened strength is needed.

SS416

High machinability is required, and the lower hardened strength and lower corrosion resistance of 416 is acceptable.

SUS 440C

A higher hardened strength or hardness than can be obtained from 420 is needed.

stainless steel 431 Corrosion Resistance

Excellent resistance to a wide variety of corrosive media. Reasonable resistance to salt water in cold southern waters but less resistant than SUS316 in tropical waters. Overall the corrosion resistance of SUS431 is approximately the same as or slightly below that of SUS304.

Performance is best with a smooth surface finish, in the hardened and tempered condition.

431 stainless steel Heat Resistance

Resists scaling in intermittent service to 925°C and in continuous service to 870°C, but is generally not recommended for use in temperatures above the relevant tempering temperature, because of reduction in mechanical properties.

431 stainless steel Heat Treatment

Full anneal – not practical for this grade – it hardens even when cooled slowly.

Process Anneal – heat to 620-660°C and air cool.

Hardened by heating to 980-1065°C, holding for about 1/2 hour then quenching in air or oil. Pre-heating at 760-790°C may be useful for complex parts or those already hardened. Temper to suit mechanical requirements, at temperatures as indicated in the accompanying table.

The tempering range 425-600°C should be avoided due to reduced impact toughness, although the effect is less marked than in most other martensitic grades.
