1.7711 / 40CrMoV4-6+QT (SA193-B16)

1.7711 / 40CrMoV4-6+QT (SA193-B16) – High-Strength Alloy Steel for Pressure Bolting

A chromium-molybdenum-vanadium alloy steel developed for high-pressure, high-temperature bolting applications, offering excellent tensile strength and creep resistance.

Hot rolled, quenched and tempered (Q+T)
(Heat-treated to meet critical requirements for pressure vessels and high-stress bolting)

• Tensile Strength (Rm): 860–1,100 MPa

• Yield Strength (Rp0.2): min. 690 MPa

• Elongation: min. 20%

• Hardness: max. 321 HBW (equivalent to approx. 35 HRC)

• Operating Temperature Range: up to 550–600 °C (depending on application)

Used in:
Petrochemical plants, pressure vessels, heat exchangers, turbines, and critical bolting in high-pressure/high-temperature systems (HPHT)

Spec:
ASTM A193 Grade B16, EN 10269:2001 (1.7711), ASME Section II (Part A/B), PED 2014/68/EU compliant
