Manufacturing Notes:
Hlau Phaj raws li ASTM A537 Chav Kawm 1, 2 thiab 3 yuav tsum raug tua cov hlau thiab ua raws li qhov zoo ntawm austenitic grain loj yuav tsum tau ntawm Specification A20 / A20M.
Txoj kev kho cua sov
Txhua daim hlau raws li ASTM A537 yuav tsum tau kho cua sov raws li hauv qab no:
ASTM A537 Class 1 daim hlau yuav tsum normalized.
Chav Kawm 2 thiab Chav Kawm 3 yuav tsum tau quenched thiab tempered. Qhov kub thiab txias rau Chav Kawm 2 yuav tsum tsis pub tsawg tshaj 1100 degree F [595 degree] thiab tsis tsawg tshaj 1150 degree F [620 degree] rau Class 3 daim hlau.
A: Siv rau ob qho tib si cua sov thiab cov khoom tsom xam.
B: Manganese tuaj yeem tshaj 1.35% ntawm kev ntsuas cua sov, mus txog qhov siab tshaj plaws ntawm 1.60%, thiab npib tsib xee yuav tshaj 0.25% ntawm kev ntsuas kub, mus txog qhov siab tshaj ntawm 0.50 %, muab qhov ntsuas kub ntsuas carbon sib npaug koob tshuaj tsis tshaj 0.57^ thaum ua raws li qhov sib npaug hauv qab no:
CE=C + Mn/5 + (Cr+Mo+V)/5 + (Ni+Cu)/15
Thaum siv qhov kev xaiv no, cov ntsiab lus ntawm manganese thiab npib tsib xee ntawm cov khoom tsom xam yuav tsum tsis txhob tshaj cov ntsiab lus ntawm kev ntsuas cua sov los ntawm ntau tshaj {{0}}.12% thiab 0.03%, feem.
Mechanical Requirements rau A537 CL1, CL2, CL3
Tensile zog thiab yield zog: Cov khoom raws li sawv cev los ntawm qhov nro-test qauv yuav tsum ua raws li qhov yuav tsum tau muaj nyob rau hauv Table 2.
Rau Chav Kawm 2 thiab Chav Kawm 3 daim hlau nrog lub npe tuab ntawm 3/4 nyob rau hauv. [20 mm] thiab hauv qab, qhov 1 1/2-in. [40 mm] dav duab plaub yuav siv tau rau qhov ntsuas nro, thiab qhov elongation yuav raug txiav txim siab hauv ib 2-in. [50 mm] gage ntev uas suav nrog cov pob txha thiab qhov uas qhia tau tias qhov loj tshaj elongation.
Peb Lub Zog
Pab pawg muaj 8 lub koom haum ua lag luam, nyob hauv Anyang, Tianjin, Hongkong thiab Singapore lub teb chaws thiab cov cheeb tsam.
Leaning ntawm Angang, ciam teb rau HBIS nyob rau sab qaum teb, cov neeg nyob ze rau Wuyang steel nyob rau sab qab teb, ib sab ntawm Shandong steel thiab Rizhao steel nyob rau sab hnub tuaj, Gnee muaj ntau thiab ntau yam khoom siv. Peb cov khoom tseem ceeb: steel phaj series xws li shipbuilding phaj, siab nkoj phaj, choj Corten steel, mining hnav resistant phaj, siab zog structural phaj, stainless hlau phaj, txias dov steel phaj, galvanized steel phaj thiab lwm yam .; Cov yeeb nkab series muaj: seamless yeeb nkab, welded yeeb nkab, API yeeb nkab, square yeeb nkab thiab lwm yam .; Bar series npog: carbon round bar, alloy round bar, stainless hlau round bar thiab lwm yam .; Profile ranges ntawm H beam, kaum sab xis, channel beam, tiaj tus bar rau kuv beam thiab lwm yam .; Kev ua cov hlau txuas ntxiv muaj xws li: qhov project tsim thiab tsim khoom, tsim vaj tsev thiab Corten steel khoom ua-ntau lawm.
