ASTM A694 F60 yog high-yield carbon steel forging material tsim tshwj xeeb rau high-pressure transmission service; nws yog siv dav hauv cov roj av, natural gas, thiab petrochemical industries rau flanges, pipe fittings, thiab piping components. Nws "F60" lub npe txhais tau tias minimum yield strength ntawm 60 ksi (415 MPa); muab ntau dua strength reserves thiab safety margins piv rau standard carbon steel, nws yog cov khoom nyiam rau medium-to-high-pressure systems uas ua haujlwm hauv sulfur-containing environments.
Cov khoom no dhau kev tswj xyuas zoo tag nrho cov txheej txheem:
1. Tswj Raw Material: Spectroscopic analysis xyuas kom ua raws li chemical composition standards.
2. Forging Process: Precision-controlled forging hauv qhov kub ntawm 950°C to 600°C.
3. Heat Treatment: Normalizing (926°C to 982°C) txhim kho grain structure.
4. Non-destructive Testing: 100% Ultrasonic Testing (UT) + Radiographic Testing (RT).
5. Pressure Testing: Hydrostatic testing ntawm 1.5 npaug ntawm tus design pressure.
6. Third-Party Certification: EN 10204 3.2 Material Certificate.
