Cov ntaub ntawv khoom

317 stainless hlau, tseem hu ua UNS S31700 thiab Qib 317, feem ntau muaj 18% mus rau 20% chromium thiab 11% mus rau 15% npib tsib xee nrog rau cov pa roj carbon, phosphorus, sulfur, silicon thiab sib npaug nrog hlau. UNS S31700 / S31703 feem ntau hu ua Stainless Steel 317 / 317L Dual Certified yog cov ntsiab lus qis ntawm Stainless Steel 317 rau cov qauv welded.

Nta thiab qhov zoo ntawm ob qho tib si Stainless Hlau 317 thiab 317 / 317L Dual Certified muaj xws li muaj zog, corrosion kuj (xws li crevice thiab pitting), siab tensile zog thiab ib tug ntau dua kev nyuaj siab-rau-rupture piv. Ob qib tiv thaiv pitting hauv acetic thiab phosphoric acids. Nrog rau kev ua haujlwm txias ntawm Stainless Steel 317 thiab 317 / 317L Dual Certified, stamping, shearing, drawing thiab heading tuaj yeem ua tiav. Tsis tas li ntawd, annealing tuaj yeem ua tau ntawm ob qib ntawm 1850 F thiab 2050 F, ua raws li qhov txias txias. Tsis tas li ntawd, txhua txoj kev ua haujlwm kub kub tuaj yeem ua tau nrog Stainless Steel 317 thiab 317 / 317L Dual Certified, ntawm 2100 F thiab 2300 F.

Vuam 317L

317L tau yooj yim welded los ntawm ntau yam ntawm cov txheej txheem vuam ib txwm (tshwj tsis yog oxyacetylene). AWS E317L / ER317L muab tub lim hlau lossis austenitic, cov pa roj carbon tsawg nrog cov ntsiab lus molybdenum siab dua li ntawm 317L, lossis cov nickel-base muab tub lim hlau nrog cov ntsiab lus chromium thiab molybdenum txaus kom tshaj qhov corrosion kuj ntawm 317L yuav tsum tau siv los vuam 317L hlau.
