Materyal ng produkto
Ang Alloys 304 (S30400) at 304L (S30403) ay parehong variation ng malawak na kinikilala at karaniwang ginagamit na 18% chromium – 8% nickel austenitic stainless steel.
Karaniwan, ang 304L ay dual certified bilang parehong 304 at 304L. Ang mababang nilalaman ng carbon nito, kasama ang idinagdag na nitrogen, ay nagbibigay-daan sa 304L na makamit ang parehong mga mekanikal na katangian gaya ng 304.
Ang parehong mga haluang metal ay nag-aalok ng paglaban sa atmospheric corrosion at mahusay na gumaganap sa moderately oxidizing at pagbabawas ng mga kapaligiran. Sa kanilang welded form, nagpapakita sila ng malakas na pagtutol sa intergranular corrosion. Pinapanatili din nila ang mahusay na lakas at tibay, kahit na sa mga cryogenic na temperatura.
Sa annealed state, ang 304/304L ay non-magnetic ngunit maaaring magpakita ng bahagyang magnetism pagkatapos ng malamig na pagtatrabaho o welding. Ang mga haluang metal na ito ay madaling hinangin at iproseso gamit ang mga karaniwang pamamaraan ng paggawa
