Product Code:SAE AMS5519
Title:Steel, Corrosion Resistant, Sheet and Strip, 18Cr - 8Ni (SAE 30301) Cold Rolled, 185 ksi (1276 MPa) Tensile Strength
Issuing Committee:Ams F Corrosion Heat Resistant Alloys Committee
Scope:This specification covers a corrosion-resistant steel in the form of sheet and strip.These products have been used typically for parts requiring moderate drawing or forming and high strength, but usage is not limited to such applications.Mechanical properties specified herein are obtained by cold working (strain hardening) and not by heat treatment. Therefore, the cold-worked product should not be heated to a temperature which adversely affects the mechanical properties or corrosion resistance before, during, or after fabrication.【英文标准名称】:Soilimproversandgrowingmedia-Extractionofaquaregiasolubleelements
