What’s up guys?!?!?! This is Michael with Michael Talks Metal back for another stainless session today. This week our topic is type 430; a stainless steel alloy with the UNS designation S43000. It is a ferritic alloy and cannot be heat treated to increase hardness and strength levels.

Typical applications require the corrosion or oxidation resistance of this 17% chromium alloy.  Elevated temperature applications are generally limited to a maximum of 1600 deg F.

Typical annealing temperature  is from  1300 to 1450 deg F.

Is 430 magnetic? Yes, 430 is magnetic

430       SAE 51430    UNS S43000

Density:      point 28 lbs per cubic inch

Mean Coefficient of Thermal Expansion from 32 -212 deg F:

5.8 microinch per inch per deg F

Machinability rating: 54 %   (of 1212)

430 Chemical Composition:

Carbon            0.12 % Max %

Manganese      1.00 % Max

Silicon              1.00 % Max

Phosphorus      0.040 % Max

Sulfur                0.030 % Max

Chromium        16.00 – 18.00 %

Nickel                0.75 % Max

Molybdenum     0.50 % Max

Copper              0.50 % Max

Tin                     0.05 % Max

Typical maximum hardness in the annealed condition:  202 BHN

Mechanical Properties in the annealed condition:

35,000 psi Yield Strength

65,000 psi Tensile Strength

25 % Elongation

Specifications for annealed condition:

AMS 5627: Bars, Forgings, Tubing, and Rings –

AMS 5503: Sheet, Strip and Plate

AMS-QQ-S-763  Bars, Shapes, and Forgings

ASTM and ASME standards for commercial applications are too numerous to detail here.
