API 5Lumbhobho wentsimbi umbhobho
Ibakala lentsimbi: L360 okanye X52 (PSL1)
Iimfuno zemichiza:
C: ≤0.28(ingenamthungo) ≤0.26(i-welded)
Mnu: ≤1,40
P: ≤0.030
S: ≤0.030
Cu: 0.50 okanye ngaphantsi
Ni: ≤0.50
Cr: ≤0.50
Mo: ≤0.15
*V+Nb+Ti: ≤0.15
* Umxholo weManganese unokunyuswa nge-0.05% kwi-0.01% nganye yokunciphisa umxholo wekhabhoni, ukuya kuthi ga kwi-1.65%
Iimfuno zeempawu zoomatshini:
Amandla esivuno: ≥360Mpa
Amandla okuqina: ≥460Mpa
Weld tensile amandla umbhobho wentsimbi oludityanisiweyo: ≥460Mpa
Elongation: ≥1940* AXC0.2/4600.9 , apho i-AXC yindawo enqamlezayo yesampulu yokuqina
Unyamezelo lwedayamitha yangaphandle yombhobho wentsimbi:
| Idayamitha yangaphandle D mm | Phelisa ngaphandle ukutenxa kwidayamitha mm | |
| Umbhobho wentsimbi ongenamthungo | Umbhobho wentsimbi odityanisiweyo | |
| < 60.3 | -0.8, +0.4 | |
| 60.3 D okanye ngaphantsi kwe-168.3 okanye ngaphantsi | -0.4, +1,6 | |
| 168.3 < D≤610 | ± 0.005D, kodwa ubuninzi ±1.6 | |
| 610 < D≤1422 | +/ - 2.0 | +/ - 1.6 |
| > 1422 | Ngesivumelwano | |
Udonga ubukhulu ukunyamezelana of intsimbi umbhobho:
| Ubukhulu bodonga t mm | Ukunyamezela mm |
| Umbhobho wentsimbi ongenamthungo | |
| 4.0 okanye ngaphantsi | +0.6, -0.5 |
| 4 <t <25 | +0.150t, -0.125t |
| 25 okanye ngaphezulu | +3.7 okanye +0.1t, nokuba yeyiphi enkulu -3.0 okanye -0.1t, thatha enkulu |
| Umbhobho odityanisiweyo | |
| 5.0 okanye ngaphantsi | + / - 0.5 | |
| 5.0 | <t <15 | Dibanisa okanye thabatha 0.1 t |
| 15 | okanye ngaphezulu | +/ - 1.5 |
Intsimbi ibakala: L360N or X52N(PSL2)
Ikhemikhali ukwakheka iimfuno:
C: ≤0.24
Si: ≤0.45
Mnu: ≤1,40
P: ≤0.025
S: ≤0.015
V: ≤0.10
Nb:≤0.05
ITi: ≤0.04
Cu: ≤0.50
Ni: ≤0.30
Cr: ≤0.30
Mo: ≤0.15
V+Nb+Ti: ≤0.15
* Umxholo weManganese unokunyuswa nge-0.05% kwi-0.01% nganye yokunciphisa umxholo wekhabhoni, ukuya kuthi ga kwi-1.65 ephezulu.
* Akukho kongezwa ngabom kweboron kuvunyelwe, intsalela B≤0.001%
Ikhabhoni ngokulinganayo:
CEP cm : ≤0.25
CEIIW : ≤0.43
* Sebenzisa i-CE xa umxholo wekhabhoni ungaphezu kwe-0.12%, kwaye usebenzise i-CE IIW xa uP cm umxholo wekhabhoni ungaphantsi okanye ulingana no-0.12%.
CEP cm = C+Si/30+Mn/20+Cu/20+Ni/60+Cr/20+Mo/15+V/10+5B
Ukuba isiphumo sohlalutyo lwe-smelting ye-B lungaphantsi kwe-0.0005%, ngoko akukho mfuneko yokubandakanya uhlalutyo lwento B ekuhlalutyweni kwemveliso, kwaye umxholo we-B unokuphathwa njenge-zero kwi-carbon elingana ne-CEP cm yokubala.
CEIIW =C+Mn/6 (C+Mo+V)/5+(Ni+Cu)/ 15
Oomatshini iipropati iimfuno:
Amandla esivuno: 360-530Mpa
Amandla okuqina: 460-760Mpa
Umlinganiselo wesivuno: ≤0.93 (kuphela kwi-D> 323.9mm umbhobho wentsimbi)
Weld tensile amandla umbhobho wentsimbi oludityanisiweyo: ≥460Mpa
Ubuncinci be-elongation: = 1940 * AXC0.2/4600.9, apho i-AXC yindawo enqamlezayo yesampuli ye-tensile.
Uvavanyo lwempembelelo ye-CVN yetyhubhu
