Anyang Longteng Heat Treatment Material CO.,Ltd is a professional heat-treating rod factory based in China, providing high strength QT treated bars and bolts. One of the most competitive materials is post-tensioning bar system.
Post-tension bar is produced from raw material 42CrMoA, which is equivalent to ASTM A192 B7, AISI 4140, etc. Anyang Longteng use its own patent technilogy to achieve heat treatment to the round bars. Q represents quenching, and T represents tempering, QT are the most important steps in heat treatment to increase steel strength and obtain a fine crystalization. Anyang Longteng post tension bar are high strength bar with superior fatigue properties. Post tension bar provides an ultimate yield strength 1100 N/mm2.
Anyang Longteng Post tension bar is available in diameters from 30 to 80mm. This is a big advantage in the market as a big range.
Advantages:
Higher yield strength;
Higher tensile strength;
High ductility;
Consistent mechanical properties;
Consistent modulus of elasticity for bars;
Enhanced fatigue performance
