Ametek Ultra 303L P/M Stainless Steel, Sintered from 6.65 g/cc Green Density

Ametek's patented Ultra Stainless Steels™ are produced by alloying the conventional austenitic compositions with a small amount of a copper-nickel-tin alloy. This results in a marked improvement in corrosion resistance, while other properties are comparable to the conventional counterparts.Mechanical property data below is from samples lubricated with 1% Acrawax C and pressed at 50 tsi. Green strength 1050 ksi. Specimens were delubricated in air for 20 min. at 950°F (510°C), then sintered in dissociated ammonia for 30 min. at 2100°F (1149°C) and cooled in the water jacketed furnace cooling zone. Dimensional change from die size -0.10%.Information provided by Ametek Specialty Metal Products.
