SA387 GR.21 CL1 Icyuma cyumuvuduko wicyuma

ASTM A387 Gr 21 CL 1 ni icyuma cya chromium molybdenum alloy icyuma kigenewe cyane cyane icyuma gisudira hamwe nubwato bwumuvuduko bugenewe serivisi yubushyuhe bwo hejuru. Ibirimo Cr 3.00% nibirimo Mo 1.00%. Buri cyiciro usibye icyiciro cya 21L, Icyiciro cya 22L, Icyiciro cya 91 nicyiciro cya 911 kiraboneka mubyiciro bibiri byingufu zingutu.ASTM A387 ICYICIRO CYA 5 Icyiciro cya 1 - Alloy ibyumaASTAST A387 GRADE 5 Icyiciro 1 Icyiciro cyiza ASTM A387 GRADE 5 Icyiciro cya 1 cyangwa chrome molybdenum icyuma gisya ibyuma bigenewe gukoreshwa muburyo bwo gusudira ibyuma bya karuboni byogosha ubushyuhe bwinshi. Wongeyeho molybdenum itanga ibikoresho byinshi byubushyuhe bukabije kandi chromium itanga imbaraga zo kurwanya ruswa. 11Icyiciro cya 1 ni ubwoko bwa plaque ya Cr-Mo-alloy ibyuma bikoreshwa muguhimba imiyoboro yubushyuhe bwo hejuru.A387 ifite amanota icumi cyangwa urwego. Ni icyiciro cya 2, icyiciro cya 12, icyiciro cya 11, icyiciro cya 22, icyiciro cya 22L, icyiciro cya 21, icyiciro cya 21L, icyiciro cya 5, icyiciro cya 9, icyiciro cya 91.

Ibipimo ngenderwaho kuri ASME SA387 Amashanyarazi

ASME

• SA20 / A20M: Ibisabwa muri rusange kubisahani byumuvuduko.
• SA370: Ikizamini cyerekana imiterere yubukorikori
• SA435 / A435M: Kubisuzumisha-ultrasonic igenzura ibyapa
• SA577 / A577M: Kugirango ultrasonic angle beam isuzume ibyapa
• SA578 / A578M: ​​Kuburyo bugororotse UT gusuzuma ibyapa byiziritse mubisabwa bidasanzwe
• SA1017 / A1017M: Ibisobanuro byerekana amasahani yamashanyarazi yamashanyarazi, chromium-molybdenum-tungsten

Ibisobanuro bya AWS

• A5.5 / A5.5M: Amashanyarazi make ya electrode yo gukingira ibyuma arc gusudira.
• A5.23 / A5.
• A5.28 / A5.28M: Kuri gazi ikingira arc gusudira
• A5.29 / A5.29M: Kuri flux cored arc gusudira.

Kuvura Ubushyuhe kuri SA387 Chrom Moly Amashanyarazi

Icyuma cya Chrome moly alloy icyuma munsi ya ASME SA387 kigomba kwicwa ibyuma, hamwe no kuvurwa nubushyuhe haba muburyo bwa annealing, normarlizing and tempering. Cyangwa mugihe byumvikanyweho nabaguzi, gukonjesha byihuse biturutse ku bushyuhe bukabije bwo guhumeka ikirere cyangwa kuzimya amazi, bigakurikirwa nubushyuhe, ubushyuhe buke bwubushyuhe bugomba kuba munsi yimbonerahamwe:

Icyiciro	Ubushyuhe, ° F [° C]
2, 12 na 11	1150 [620]
22, 22L, 21, 21L na 9	1250 [675]
