10 # Seamless steel yeeb nkab
Lus piav qhia luv luv:
Khoom specification:
Sab nraud txoj kab uas hla ntawm cov yeeb nkab steel 20-426
Hlau yeeb nkab phab ntsa thickness ntawm 20-426
Tshuaj muaj pes tsawg leeg:
● No. 10 seamless steel yeeb nkab tshuaj muaj pes tsawg leeg:
Carbon C: 0.07 ~ 0.14″ silicon Si: 0.17 ~ 0.37 Manganese Mn: 0.35 ~ 0.65 Sulfur S: ≤0.04 Phosphorus P: ≤0.35 chromium Cr: ≤0.15 Nickel Ni: ≤0.25 ≤20.
Mechanical Properties:
Mechanical zog ntawm No. 10 seamless steel yeeb nkab: Tensile zog σb (MPa): ≥410 (42) Yield zog σs (MPa): ≥245 (25) elongation δ5 (%): ≥25 seem shrinkage (%) : ≥5 , hardness: unheated, ≤156HB, qauv loj: 25mm.
High quality carbon steel qauv:
No. 10 seamless steel yeeb nkab tsis muaj lwm cov ntsiab lus alloy (tshwj tsis yog cov khoom seem) tshwj tsis yog cov pa roj carbon (C) thiab qee qhov nyiaj ntawm silicon (Si) rau deoxidation (feem ntau tsis tshaj 0.40%), manganese (Mn) (feem ntau tsis ntau tshaj 0.80%, mus txog 1.20%) alloy ntsiab.
Xws li cov hlau yuav tsum muaj cov tshuaj muaj pes tsawg leeg thiab cov khoom siv kho tshuab.Cov ntsiab lus ntawm sulfur (S) thiab phosphorus (P) feem ntau tswj qis dua 0.035%.Yog tias nws tswj tau qis dua 0.030%, nws yog hu ua cov hlau zoo, thiab "A" yuav tsum tau ntxiv tom qab qib, xws li 20A;Yog tias P tswj tau qis dua 0.025% thiab S tswj qis dua 0.020%, nws yog hu ua cov hlau zoo ntxiv, thiab "E" yuav tsum tau ntxiv tom qab qib kom pom qhov txawv.Rau lwm cov residual alloying ntsiab coj mus rau hauv cov hlau los ntawm raw cov ntaub ntawv, xws li chromium (Cr), npib tsib xee (Ni), tooj liab (Cu), thiab lwm yam, cov ntsiab lus ntawm Cr≤0.25%, Ni≤0.30%, Cu≤0.25%.Qee hom ntawm manganese (Mn) cov ntsiab lus txog li 1.40%, hu ua manganese steel.
No. 10 seamless steel yeeb nkab hnyav xam cov mis: [(sab nraud txoj kab uas hla - phab ntsa thickness) * phab ntsa thickness] * 0.02466 = kg / m (qhov hnyav ib meter)
