While both alloys are stainless animate and actual agnate in content, there are some key differences, the percentages of chromium, nickel and carbon. Blazon 301 was developed to be a Oven Accessories another to Blazon 304. In adjustment to accomplish the adapted lower cost, the alloy’s blueprint was accurately developed to cover beneath of the added big-ticket elements nickel and chromium and college percentages about of bargain carbon. As expected, amount /content tradeoff does accept a abeyant aftereffect on the achievement envelope of Blazon 301 over the activity assumption of the sink.

Type 304 contains just 0.08% max carbon, or about bisected the 0.15% max carbon agreeable of Blazon 301. While the differences in percentages may assume minuscule, their appulse on the steel’s achievement is significant. Blazon 301 has acceptable cartoon and basal characteristics, acknowledgment to its college carbon and lower nickel content, authoritative it hardly beneath big-ticket to fabricate. This does comes with a cede to bane resistance. Its college carbon agreeable can could cause Blazon 301 to display sensitization, the accumulation of chromium carbides at the atom boundaries during adjustment or laser cutting. Over time, this can aftereffect in intergranular bane or “weld decay” at the sensitization zone. In adjustment to anticipate this corrosion, Blazon 301 accept to abide a accessory annealing action to deliquesce the chromium carbides. The bond birthmark accept to aswell be removed by alkali and passivation to restore Blazon 301’s bane attrition at the bond or laser cut edges. Blazon 304 will not acquaintance sensitization or intergranular corrosion, and accordingly not crave bactericide accessory operations.

Type 304 will aswell display a greater attrition to pitting adjoin Blazon 301 if in acquaintance with chloride solutions. ASTM G48 A pitting analysis after-effects showed Blazon 301 Stainless Steel Kitchen Sinks a accumulation accident of 0.0105 g/cm2 if apparent for a aeon of 72 hours at 22? C in acerbic chloride acid, while Blazon 304 apparent a accumulation accident of just 0.0063 g/cm2.
