ASTM A131 yog ib qib qauv ntawm steel phaj siv yuav luag tshwj xeeb hauv kev lag luam shipbuilding. Qib no txhais tau tias yog lub zog zoo tib yam nrog cov txiaj ntsig tsawg kawg nkaus ntawm 34KSI (235Mpa). Cov ntawv thov suav nrog cov nkoj nkoj, cov khoom siv hauv hiav txwv thiab kev tsim nkoj. Cov qib no kuj tau lees paub los ntawm American Bureau of Shipping (ABS)

Kev taw qhia luv luv ntawm marine steel phaj thiab A131 lub zog zoo tib yam Tshuaj muaj pes tsawg leeg thiab mechanical zog

Kev taw qhia luv luv ntawm marine steel phaj thiab A131 lub zog zoo tib yam

Marine steel phaj hais txog cov qauv hlau siv hauv nkoj tsim. Nws suav hais tias yog qib marine thiab yuav tsum muaj peev xwm tiv taus cov teebmeem corrosive uas muaj nyob rau hauv ib puag ncig dej. Txhawm rau ua tiav qhov no, cov ntsiab lus tshwj xeeb alloying tau ntxiv rau cov qib no txhawm rau tiv thaiv kev tiv thaiv corrosion.Thaum cov pa roj carbon feem ntau tsis haum rau cov chaw nyob hauv dej hiav txwv, muaj ntau ntau qib marine carbon steels uas tau pom zoo los ntawm cov koom haum sib txawv rau kev siv nkoj tsim.

Cov qauv hlau rau lub nkoj hulls tau muab faib ua cov chav kawm muaj zog raws li nws qhov tsawg kawg nkaus yield zog: lub zog dav dav hlau thiab siab lub zog steel. Maine steel phaj hais txog kub dov steel phaj ua raws li cov kev cai ntawm lub classication haiv neeg rau kev tsim kho ntawm lub nkoj hull lug. Lub zog steel s ntawm Tuam Tshoj Classification Society tau muab faib ua plaub qib zoo: A B D thiab E.

Muaj 9 lub koom haum kev faib tawm tseem ceeb hauv ntiaj teb.

Cov qib no kuj tau lees paub los ntawm American Bureau of Shipping (ABS)

Qhov kev qhia tshwj xeeb no suav nrog cov qauv hlau daim hlau, cov duab, tuav thiab rivets npaj rau kev siv hauv nkoj tsim.
Ordinary zog- Qib A B D CS thiab E nrog cov ntsiab lus qis kawg nkaus ntawm 34 ksi (235MPa)

Shipbuilding yog lub hauv paus rau Amelikas tus kheej thiab American ingenuity ci nyob rau hauv nws submarines, yachts, cruise ships, thiab aircraft carriers. Cov nkoj loj pib nrog cov qib siab zoo marine qib steel phaj thiab Gnee txaus siab los muab kev lag luam hauv Asmeskas kev lag luam nrog marine thiab offshore steel uas yog corrosion-resistant thiab tawv, ua kom pom kev txo qis, txawm tias nyob rau hauv txias txias, thiab muaj zog zog los tiv thaiv kev raug mob thiab kev vibration. Tag nrho peb cov phaj qib marine ua tau raws li cov qauv tsim los ntawm ABS (American Bureau of Shipbuilding), ASTM, thiab API (American Petroleum Institute). Peb yog cov chaw tsim khoom ntseeg siab ntawm marine & offshore steel phaj thoob ntiaj teb thiab kev pabcuam nkoj tsim khoom
