This paper is focused on the welding of low alloy steels S355 and AH36 in thicknesses 6, 8 and 10 mm in T-joint configuration using either autogeneous laser welding or laser-arc hybrid welding
(PDF) Modern high strength Nb-bearing structural steelsThis led to savings of 15 % in weight and 2.2 million in cost compared with using S355 steel [1,2]. beams made from high strength steel. steel. It can be seen that the dilute additions
Steel is still the most widely used metal and an understanding of its structure and properties is useful for engineers, technologists and technicians in many fields. This publication provides a basic introduction to the metallurgy of steels for the
British Stainless Steel AssociationThe British Stainless Steel Association (BSSA) exists to promote and develop the manufacture and use of stainless steel across the UK and Ireland. Based in Sheffield, the Association provides marketing support, technical advice, information, training and education in all aspects of stainless steel.
Effect of joint design on ballistic performance of Feb 01, 2014 · The parent metal (PM) used in this study was 18 mm thick high strength low alloy Q&T steel closely confirming to AISI 4340 specification.The heat treatment adopted for the steel was to austenitise at a temperature of 900 °C followed by oil quenching.Subsequently, the steel was subjected to tempering at 250 °C.The chemical composition of PM and filler metal used in this investigation are
types of Ni-Cr-B-Si alloy powders with different contents of alloying elements were deposited on 50-mm-diameter S355 carbon steel rods using a continuous wave IPG fiber laser with a wavelength of 1.07 m and laser powers of 800-1000 W. Chemical compositions of the coating and substrate materials are presented in Table 1.
Evolution of microstructure and properties in laser Colmonoy 69 powder from Wall Colmonoy Ltd. was deposited on S355 steel rods with 50 mm diameter using a continuous wave IPG fiber laser with wavelength of 1.07 µm. A defocused laser beam was applied with a laser spot size of around 3.5 mm on the substrate surface.
Microstructures and immersion corrosion behavior of laser Feb 25, 2018 · The amorphous Al-Ni coatings with the Al and Ni mass ratios of 3:2, 3:1 and 4:1 are sprayed on S355 structural steel, which are composed of alloy peaks and amorphous peaks, among them, the alloy peaks are Al-Fe alloy, AlCrFe 2 and Ni 2 MnAl, while the amorphous peaks are Al-Fe and Ni-Mn-Al alloys. The chemical elements are mutually diffused between the Al-Ni coating and the

What is Corten Weathering Steel?Weathering steel, best-known under the trademark COR-TEN® steel, is a group of steel alloys which were developed to obviate the need for painting, and form a stable rust-like appearance if exposed to the weather for several years. Weathering steel has increased resistance to atmospheric corrosion when compared to other steels.
