Lintlha tsa sehlahisoa

Letlapa la tšepe le phahameng la lihlahisoa la ASTM A514 Grade K le sebelisoa moo ho hlokahalang tšepe e chesehang, e machable, e matla haholo ho boloka boima ba 'mele kapa ho fihlela litlhoko tsa ho qetela tsa matla. Alloy steel plate A514 Gr K e atisa ho sebelisoa e le tšepe ea mohaho mohahong oa mohaho, li-crane kapa mechine e meng e meholo e tšehetsang meroalo e phahameng. Ho fihlela joale re ka fana ka botenya bo boholo bakeng sa poleiti ea tšepe e matla ea A514 Gr.K e fihlang ho limilimithara tse 300 ka kalafo ea mocheso e timang le e halefileng.

ASTM A514 Structural Steel Plate ke poleiti ea tšepe e oelang tlas'a sekhele sa lipoleiti tsa tšepe tsa Quenched and Tempered Alloy. Lipoleiti tsena li fumana kalafo ea Q&T moo li futhumatsoang le ho pholile kapele. Matla a tlase a tlhahiso a 100 ksi a etsa hore lipoleiti tsa tšepe tse hananang le ASTM A514 li be thata haholo 'me li sebelisoe hantle. Ho latela maemo a ASTM, lipoleiti tsena tsa tšepe tsa High Strength Alloy (HSA) li emela:
