431 stainless steel As a martensitic stainless steel with a 17% chromium and 2.5% nickel content it is usually supplied in the hardened but still machineable condition. It offers good corrosion resistance in mild marine and industrial atmospheres where high tensile and yield strength with excellent toughness are required.

Mechanical Properties

 

The mechanical properties for grade 431 stainless steels are listed in the table below.The bend test is obtained around a diameter of the bend factor multiplied by the steel thickness.

Unless otherwise indicated,a grade designation originally assigned by the American Iron and Steel Institute(AISI).

Yield Strength shall be determined by the offset method at 0.2% in accordance with Test Dethods and Definitions A370 .Unless otherwise specified (see Specification A480/A480M,paragraph 4.1.11,Ordering information),an alternative method of determining yield strength may be based on total extension under load of 0.5%.

 

Either Brinell or Rockwell B Hardness is permissible.

 

Bend tests are not required for chromium steels(ferritic or martensitic) thicker than 1 in.

[25 mm] or for any austenitic or duplex(austenitic-ferritic)stainless steels regardless of thickness.

 

Key Properties:

The specified properties are for bar products in ASTM A276. The properties may not be necessarily similar to other forms such as forgings and plates.
