SAE8620H
SAE認(rèn)證
美國(guó)機(jī)動(dòng)車工程師學(xué)會(huì)（ SAE）成立于1905年，是國(guó)際上最大的汽車工程學(xué)術(shù)組織。研究對(duì)象是轎車、載重車及工程車、飛機(jī)、發(fā)動(dòng)機(jī)、材料及制造等。SAE所制訂的標(biāo)準(zhǔn)具有權(quán)威性，廣泛地為汽車行業(yè)及其他行業(yè)所采用，并有相當(dāng)部分被采用為美國(guó)國(guó)家標(biāo)準(zhǔn)。
SAE機(jī)動(dòng)車標(biāo)準(zhǔn)是機(jī)車行業(yè)的技術(shù)標(biāo)準(zhǔn)。美國(guó)機(jī)動(dòng)車工程師學(xué)會(huì)（SAE）的認(rèn)證：規(guī)定了市場(chǎng)上銷售的汽車配件（SAE認(rèn)證）的標(biāo)準(zhǔn)，這些配件不作為供應(yīng)商的批量銷售。
SAE8620對(duì)應(yīng)于國(guó)標(biāo)20CrNiMo 此鋼種適合于加工齒輪，淬透性比較好。
SAE certification
American Society of Automotive Engineers (SAE) was founded in 1905, is the world's largest automotive engineering academic organization. The research object is the car, truck and engineering vehicle, aircraft, engine, materials and manufacturing, etc.. The standards developed by SAE are authoritative and widely used in the automotive industry and other industries, and a considerable part of the United States national standards are adopted.
SAE motor vehicle standard is the technical standard of the locomotive industry. The American Society of Automotive Engineers (SAE) certification: the market for the sale of auto parts (SAE certification) standards, these parts are not as a supplier of bulk sales.
SAE8620 corresponds to the national standard 20CrNiMo of this kind of steels suitable for machining gear, good hardenability.
