Sichuan Hirofu Tshwj xeeb Steel tuam txhab yog ib qho ntawm cov neeg tsim khoom thiab lwm tus neeg ntawm S2 cuab tam hlau hauv Suav teb. Nrog ntau tshaj 20 xyoo kev paub, peb lub Hoobkas muaj cov khoom lag luam zoo hauv Suav teb nrog cov nqi sib tw. Txais tos tiv tauj peb rau kev pabcuam lag luam wholesale.
Tom qab ob peb xyoos kev txhim kho, Sich Hirof tsuas yog kev tswj hwm steel, thiab tsim cov khoom lag luam zoo ntau lawm, thiab ua kom tiav cov khoom lag luam
S2 yog chav kawm ntawm cov cuab yeej siv hlau tsim los tiv thaiv breakage los ntawm kev poob siab. Raws li Aisi cov kev faib tawm muaj xya hom, sau npe S1 rau S7.
S2 yog ib txwm siv los tsim cov ntsia hlau nrog hex loj 6.35mm
Lub ntsiab
Shock - Tiv thaiv cov hlau yog tsim los muaj kev cuam tshuam siab (kev muaj zog), nrog rau lwm cov khoom xws li muaj zog, Hardness. Silicon yog ib qho ntxiv rau cov chav kawm ntawm cov hlau, vim nws muab cov kev tsis txaus siab tsis txaus thiab nce tawv. [1]
Cov ntawv thov rau kev poob siab - Tsis kam tua cov hlau, nrog rau kev lom zem, thiab punches. [1] S2 hlau kuj tseem siv los ua cov pob bearings rau kev lag luam tsuas. [2] Lawv kuj tau siv rau cov ntsia hlau thiab cov tsav tsheb. [3]

S2 alloy steel yog ib tug poob siab - Tsis kam ua hom steel hom. Nws khaws tau zoo duction txawm nyob rau hauv cov xwm txheej tawv, uas tso cai rau nws ua hauv cov ntawv thov kev poob siab yuav kis tau rau cov alloy. Poob siab - Tsis kam lees cov cuab yeej hlau zoo li qhov no tau xaiv ua cov pab pawg S cov hlau.
