ASTM A537 Qib 1yog ib tug normalized, tshav kub-kho carbon-manganese-silicon steel phaj tsim rau fusion-welded siab hlab ntsha, boilers, thiab cia tanks, muab lub zog siab dua li cov pa roj carbon steel rau nruab nrab- qhov kub thiab txias kev pab xav tau zoo toughness, nrog rau cov kev siv nyob rau hauv cov roj, roj, thiab petrochemical indust. Cov yam ntxwv tseem ceeb suav nrog kev txhim kho tensile/yield zog vim normalization, teev cov tshuaj muaj pes tsawg leeg (xws li, max 0.24% Carbon, 0.70-1.60% Manganese), thiab tsim nyog rau kev siv kub tsawg.
Tshuaj muaj pes tsawg leeg
Lub ntsiab | Kev sib xyaw (%) |
|---|---|
Cov pa roj carbon (C) | 0.24 max |
Manganese (Mn) | 0.70-1.35 (≤40mm) 1.00-1.60 (>40mm) |
Phosphorus (P) | 0.035 max |
Sulfur (S) | 0.035 max |
Silicon (Si) | 0.15-0.50 |
Copper (Cu) | 0.35 max (yog tias muaj) |
Nickel (Ni) | 0.25 max (yog tias muaj) |
Chromium (Cr) | 0.25 max (yog tias muaj) |
Molybdenum (hli) | 0.08 max (yog tias muaj) |

Cov khoom tseem ceeb ntawm ASTM A537 Class 1 yog dab tsi?
Nws muaj nruab nrab mus rau siab tensile thiab tawm los lub zog, zoo ductility, thiab zoo heev notch toughness, tshwj xeeb tshaj yog tom qab normalizing. Cov khoom no ua rau nws tiv taus cov pob txha tawg nyob rau hauv thermal cycling thiab qis - qhov kub thiab txias.
ASTM A537 Class 1 txawv li cas ntawm Class 2 thiab Class 3?
Tag nrho peb chav kawm yog cov hlab ntsha siab nyob rau hauv tib tus qauv, tab sis lawv txawv nyob rau hauv lub zog thiab toughness theem. Chav Kawm 1 muaj lub zog qis dua piv rau Chav Kawm 2 thiab Chav Kawm 3, tab sis muab cov tawv tawv zoo, ua rau nws haum rau nruab nrab thiab qis - qhov kub thiab txias.
