The High-Strength, Low-Alloy (HSLA) steel program was initiated by the U.S. Navy to meet objectives for the reduction of shipbuilding costs by development of more weld-able steels to meet the strength and toughness requirements of HY-80 (540 MPa yield strength). HSLA-80 steel is a low carbon, copper precipitation strengthened steel based

It is possible it is a weathering grade, which requires some low alloy such as 1 percent nickel to control the rusting of nontreated surfaces. The low amount of alloy would likely boost the mechanical properties, giving it a higher strength classification.


HIGH STRENGTH LOW ALLOY STEEL (HSLAS) For high strength or Structural Steel (SS) applications, Hot Rolled Steels are also available (shown in Table 2). HSLAS is intended for applications where greater strength or weight savings are important. The increased strength of HSLAS is achieved from niobium (Nb) or vanadium (V) additions.

Oct 11, 2019 · The special designed HSLA (High Speed Low Alloy) Steel is most commonly used in Naval Steel Structures and aircraft structures due to its indigenous properties. The aim of this paper is used to investigate the effect of shielding gases in the Gas Tungsten Arc Welding process. DMR 249A [HSLA Microstructure and mechanical properties of HSLA-100 Microstructure and mechanical properties of HSLA-100 steel Mattes, Victor R. Monterey, California:Naval Postgraduate School precipitation ftrengthened high-strength, low-alloy (HSLA) plate steel has been a key element of the U.S. Navy's efforts weld sequencing requirements, weather protection, constraint reduction,

The Effect of Welding Parameters on Microstructural and

ranges were tried in the welding laboratory, and then according to the penetration and visual tests the acceptable welding parameters were selected. Thus, the microstructural and mechanical properties of submerged arc welding (SAW) welds of 25 mm thick S960QL HSLA steel according to the selected parameters were found out, instead of comparing the The Optimization of Process Parameters and welded DP980 and HSLA steel sheets. They stated that the tensile strength of the dissimilar welds was lower than DP welds. Xu et al. [6] investigated microstructural and mechanical properties, and Parkes et al. [7] reported the fatigue properties of laser welded DP and HSLA joints with varying weld geometries.


Jun 25, 2008 · Depending on the joint design and the load path (the area that will carry the bulk of the stress of a finished product) welders will often need to match the filler metal strength to the lower strength steel. As an example, when welding a HSLA steel (85 ksi yield strength) to A36 steel (36 ksi yield strength minimum), welders would choose a 70 grade flux-cored or metal-cored wire with 70 ksi High-Strength Low-Alloy Steels - ASM InternationalHSLA Steel Categories. High-strength low-alloy steels include many standard and proprietary grades designed to provide specific desirable combinations of properties such as strength, toughness, formability, weld-ability, and atmospheric corrosion resistance. These steels are not consid-
