HSLA-65ASTM A 945HAZ toughnessweld metal toughnessSMAWGMAWFCAWSAWHSLA-65 steel (ASTM A945) is being considered to replace higher strength steels (HSS) such as DH-36. However, the 70-series consumables (70 ksi [482 MPa] minimum transverse weld tensile strength) used to join HSS (71 ksi ...
tensile strengths 3 种钢都表现出在低应变下的弹性变形行为(应力和应变 成线性关系)和高应变下的塑性变形行为(应力和应变为 非线性关系)。 普通碳素钢和HSLA 钢表现出相似的塑性 屈服行为, 两种钢在加工硬化发生前都存在一个屈服台 阶, 即恒定载荷下的屈服现象。 然而双相 HSLA 钢的弹 ...

and 0.3wt.% Mo that provide weld metals characterized by an A r3 of 690°C, a CEN of 0.29, and a (B F M S ) of 30°C are expected to consistently overmatch the minimum specified tensile strength of HSLA-65 steel while offering a minimum CVN impact toughness of 41J at 40°C (30...
HSLA 100 steel boasts a higher strength, lower weight, and good machinability and ductility compared to conventional mild carbon steel grades.
Weld metal tensile, hardness and CVN impact toughness testing as well as microstructural studies using transmission electron microscopy were conducted. The ULCB weld metal was relatively insensitive to cooling rate, resulting in good strength and toughness values over a wide range of t{sub 8-5} ...
