ASTM A276 Hom 304 Stainless Hlau Qws

Qib 304 stainless hlau yog tus nqi nruab nrab lub zog austenitic stainless hlau alloy. 304 stainless hlau puag ncig tuav yog ib txwm muab nkag rau hauv kev kho cua sov.

GNEE muab ASTM A276 Hom 304 stainless hlau tuav, sib npaug rau UNS S30400 / JIS SUS304 / EN 1.4301. Raws li austenitic stainless hlau muaj 18-20% Cr thiab 8-10.5% Ni, nws muaj kev tiv thaiv corrosion zoo heev, formability thiab weldability. Nws cov khoom siv kho tshuab suav nrog lub zog tensile Ntau dua lossis sib npaug ntawm 515 MPa, lub zog tawm los Ntau dua lossis sib npaug rau 205 MPa thiab elongation Ntau dua lossis sib npaug li 40% ntawm chav tsev kub. Ntau lawm raws li ASTM A479 kuj muaj raws li kev thov. Ntxiv rau kev xa khoom rau ASTM A479 304 stainless hlau tuav muaj xws li normalized, quenched, annealed thiab tempered xeev.

GNEE muaj puag ncig, hexagonal thiab square tuav nyob rau hauv diameters ntawm Ø1 mus rau 300 mm thiab ntev los ntawm 1 mus rau 6 m los yog ntev dua, nrog rau nto finishes xws li dub, pickling, polishing thiab kaj kos duab. Cov kev pabcuam tshwjxeeb xws li txiav kom loj, tev, sib tsoo thiab kho cua sov yog muab. Tag nrho cov khoom yog MTC, SGS thiab EN certified 10204 3.1. Lub sij hawm xa tuaj rau qhov ntau thiab tsawg yog 7-12 hnub. Cov kab no tau siv dav hauv kev ua tshuaj lom neeg, kev lag luam zaub mov, kev tsim kho, tshuab tsim khoom thiab cov khoom siv hauv hiav txwv.
