FAQ

Q1: Qhov txawv ntawm UNS S31803 thiab S32205 lub luj tshib yog dab tsi?
A: S32205 yog lub siab -nitrogen txhim kho version ntawm S31803. Nws muaj cov tshuaj lom neeg ntau dua thiab txhim kho corrosion kuj. Peb lub luj tshib feem ntau yog "Dual Certified" kom ua tau raws li ob qho qauv.

Q2: Puas yog vuam 2205 lub luj tshib nyuaj?
A: Tsis yog nrog txoj hauv kev zoo . 2205 muaj qhov weldability zoo heev. Peb pom zoo kom siv ER2209 muab tub lim hlau thiab tswj qhov kub ntawm qhov sib cuam tshuam (hauv qab 150 degree) kom ntseeg tau tias qhov sib npaug ntawm cov ferrite- austenite theem.

Q3: Vim li cas thiaj xaiv 2205 tshaj 316L rau kev siv dej hiav txwv?
A: 316L muaj PREN ntawm ~ 24, ua rau nws yooj yim rau pitting hauv dej hiav txwv stagnant. 2205 muaj PREN ntawm ~ 35, muab kev tiv thaiv zoo tshaj plaws tiv thaiv cov tshuaj chlorides thiab muaj zog tiv thaiv siab rau siab - siab ntws yaig.
