ASTM A36 / A283-C / A516 (Qib 55, 60, 65) / A572 (5, 70) Lub Zog Lub Zog Hlau

Cov phiaj hlau hlau, txhais los ntawm Astm cov qauv, yog siv dav hauv cov khoom lag luam hauv cov txheej txheem, thiab hnyav Hauv qab no yog cov ncauj lus piav qhia ntxaws thiab cov ntsiab lus ntawm txhua qib:

1. ASTM A36 Carbon Cov Qauv Hlau Hlau

ASTM A36 yog cov hlau uas muaj cov roj ntsha uas muaj cov roj ntsha feem ntau muaj nuj nqis rau nws qhov sib npaug ntawm lub zog, formability, thiab pheej yig.

 

Cov Khoom Siv Tseem Ceeb:

Tshuaj Muaj Tshuaj: C Tsawg dua li lossis sib npaug nrog 0.25%, mn 0.80-1.20%, s tsawg dua lossis sib npaug lossis sib npaug lossis sib npaug rau 0.40%.

Cov Khoom Siv Neeg Kho Tshuab:

Tos lub zog: ntau dua los yog sib npaug rau 250 MPa (36 KSI).

Tensile lub zog: 400-550 mpa (58-79 ksi).

Elongation: ntau dua los yog sib npaug rau 20% (hauv 200mm koob qhia hais tias).

2. Astm A283 - c cov phaj tsawg

ASTM A283 {- C yog qhov qis- Lub zog cov hlau rau cov khoom siv tsis yog cov khoom lag luam siab.

 

Cov Khoom Siv Tseem Ceeb:

Tshuaj Muaj Tshuaj: C Tsawg dua lossis sib npaug rau 0.27%, mn tsawg dua lossis sib npaug nrog 0.90%, p tsawg dua lossis sib npaug lossis sib npaug nrog 0.05%.

Cov Khoom Siv Neeg Kho Tshuab:

Tos lub zog: ntau dua los yog sib npaug rau 170 MPa (25 KSI).

Lub zog tensile: 310-440 mpa (45-64 ksi).

Elongation: ntau dua los yog sib npaug rau 22% (hauv 50 hli gauge).

3. ASTM A516 (Qib 55, 60, 65) Av Hlau Hlau Hlau

ASTM A516 yog cov roj carbon steel tsim rau kev mob -}}} kub siab cov hlab ntsha los ntawm tensile lub zog.

 

 

 

 

 

 

 

Cov Khoom Siv Tseem Ceeb:

Tshuaj Muaj Tshuaj: C Tsawg dua lossis sib npaug ntawm 0.30% (MAR 0.79-1.30%, s tsawg dua lossis sib npaug lossis sib npaug lossis 0.23-05%.

Cov Khoom Siv Neeg Kho Tshuab(los ntawm qib):

Teem nqi	Yield zog (min)	Tensile lub zog ntau yam	Elongation (min)
A516 Gr 55	240 MPa (35 ksi)	415-550 mpa (60-80 ksi)	22%
A516 GR 60	275 MPa (40 Ksi)	450-585 Mpa (65-85 KSI)	21%
A516 Gr 65	310 MPA (45 KSI)	485-620 MPa (70-90 Ksi)	20%

Kev Cuam Tshuam: Xav tau Charpy V - tsis tau sim ntawm {}} 30℃(xaiv tau, ib qho kev thov cov neeg siv khoom).

Tus me nyuam: Neverized (los xyuas kom muaj kev nyuaj) lossis quenched -} temper tempered.
