Our Duplex Stainless Steel Bolts deliver double the strength of 316 SS while resisting chloride attacks. With 22% chromium, 5% nickel, and 3% molybdenum (per ASTM A276), they achieve PREN values >{{035 -}} proven} Ua kom muaj zog kom tiv taus 100, 000+ ppm Chlorides hauv Astm G48 kuaj.
Txias-forged taub hau muab 750 tensile zog (tshaj li asme sa320 l43 zoo meej rau ntug dej hiav txwv ntug dej uas cov tshuaj tsuag caj dab. Thib Peb Cov Lus Qhia Qhia<0.01mm/year pitting in seawater at 30°C. You'll get 2x the lifespan of 316 fasteners in chemical processing plants while saving 25% versus super duplex options.
Kev Ua Hoobkas
Peb muab ob qho tag nrho: passivated (ib qho ittm A967) los txhawb cov txheej corrosion tsis kam, thiab sandblasted (RA 25-50μm) rau cov xim pleev xim zoo dua hauv cov haujlwm sab nraum zoov. Cov txheej txheem passivation tshem tawm cov hlau dawb, ua rau lawv 35% ntau tiv taus rau chloride corrosion dua tsis kho bolts.
Ntau lawm lub zog
Raws li cov cuab yeej siv hauv Suav nrog 10 xyoo muab EU Offshore thiab tshuaj lom neeg cov kab mob khaub thuas taub hau thiab 7 xov paj ntxiv, ua 3,800 tons txhua xyoo. Peb cov khoom siv raw undergoes ib tug me nyuam tshwj xeeb /50 ferrite / austenite / austenite / austenite / austenite, soj ntsuam ntawm peb tus kheej 1%).
Peb khaws cia 220-350 tons hauv Tshuag ntawm peb Qingdao Warehouse, npog ntau los ntawm ¼ "rau 2" thiab ntev 1 "txog 20". Cov lus nug tshiab nyob rau hauv lub sijhawm tiag tiag ntawm peb lub vev xaib, thiab FOB Qingdao Kev Thauj Khoom rau hauv-Tshuag Bolts mus rau hauv-Tshuag thaum koj cov neeg yuav tsum khaws cov phiaj xwm.
Tuam Txhab Koom Tes
Kev txiav txim tshaj 45 tons tau txais 1.5% luv nqi, ntxiv rau kev ua haujlwm pub dawb thiab 15% ntawm kev thauj khoom hiav txwv.
Ntawm no yog peb qhov kev lees paub: yog tias cov qauv siv hluav taws xob tsis sib xws li ANTM A193 cov qauv neeg kho tshuab lossis muab teeb meem hloov pauv hauv 8 xyoos, peb yuav hloov lawv li ntawm 6 hnub thiab rov qab txhua tus nqi thauj khoom. Peb tseem muab tus nqi 35 hnub ntsuas ntawm kev paub meej, nrog rau 2% rov ua kom luv luv rau cov neeg siv rov qab ua ntej 3 lub hlis.
