SPA-Hyog ib lub siab -lub zog qis- alloy weathering steel ua raws li ntau yam qauv thoob ntiaj teb, suav nrog AISI, ASTM, BS, DIN, thiab JIS.
Ua los ntawm kub dov, SPA-H corten steel phaj thiab coil yog tsim tshwj xeeb rau kev siv cov qauv uas raug rau cov huab cua hnyav.
By adding small amounts of alloying elements such as copper (Cu), chromium (Cr), nickel (Ni), and phosphorus (P) to ordinary carbon steel, SPA-H weathering steel forms a dense and stable oxide (patina) layer on its surface during atmospheric exposure. Cov txheej txheem tiv thaiv no ua rau txhim kho corrosion kuj, ncua kev pab cuam lub neej thaum txo qhov xav tau kev pleev xim lossis txheej txheej.
Piv nrog cov pa roj carbon steel, SPA-H weathering steel muaj 2-8 npaug siab dua atmospheric corrosion resistance, thiab nws txheej durability yog 1.5-10 npaug ntev dua.
Ntxiv rau cov huab cua tsis zoo, SPA-H steel muab lub zog zoo, toughness, plasticity, weldability, hnav tsis kam, qaug zog tiv thaiv, thiab siab - kub ua haujlwm, ua rau nws tsim nyog rau kev thov cov qauv siv.

SPA-H corten steel yog dav siv nyob rau hauv lub thawv ntim, tsheb ciav hlau, txuas hniav, yees, roj derricks, kev tsim kho chaw nres nkoj, offshore roj platforms, thiab cov khoom siv tshuaj lom neeg los yog roj av uas ua haujlwm nyob rau hauv ib puag ncig uas muaj hydrogen sulfide thiab lwm yam corrosive media.
Spa H khoom yog dab tsi?
Raws li Spa-h steel coil cov khoom yog cov huab cua huab cua, nws tsim cov patina tiv thaiv ntawm qhov chaw uas ua rau nws zoo li rustic. Cov tshuaj muaj pes tsawg leeg ntawm JIS g3125 spa-h strip muaj xws li carbon, silicon, manganese, phosphorus, sulfur, tooj liab, chromium thiab nickel.
Spa-h steel sib npaug yog dab tsi?
Kev sib npaug thoob ntiaj teb ntawm qib SPA-H (Nyiv: JIS ) Hla cov lus siv rau Steel SPA-H (JIS ) thiab nws qhov sib npaug European S355J0WP (1.8945)
Cov tshuaj muaj pes tsawg leeg ntawm SPA-H Steel yog dab tsi?
Cov ntsiab lus tseem ceeb suav nrog carbon (C), manganese (Mn), silicon (Si), chromium (Cr), thiab tooj liab (Cu). Lawv cov ntsiab lus raug tswj nruj me ntsis kom ntseeg tau tias cov khoom siv kho tshuab thiab huab cua tsis kam.
Yuav ua li cas tswj SPA-H Steel?
SPA-H steel yuav tsum tau saib xyuas tsawg kawg nkaus. Ib txheej xeb ruaj khov tiv thaiv cov hlau. Kev tu tsis tu ncua kom tshem tawm cov plua plav lossis cov khib nyiab thiab zam kom tsis txhob raug dej ntev yog txaus.
SPA-H hlau tuaj yeem welded?
Yog lawm. Tsawg-hydrogen arc vuam lossis roj tiv thaiv vuam raug pom zoo. Preheating thiab qeeb txias tom qab vuam pab tiv thaiv kev tawg.
