AWS B2.1-BMG:2005 1 Base Metal Grouping for Welding Procedure and Performance Qualification 1. Scope This publication is an extract of AWS B2.1, Specification for Welding Procedure and Performance Qualification, and is identical to Annex IV, Base Metal Grouping, in the 2005 edition of that standard. DESIGN GUIDELINES FOR THE SELECTION AND USE OF Reference is often made to stainless steel in the singular sense as if it were one material. Actually there are over 50 stainless steel alloys. Three general classifications are used to identify stainless steels. They are:1. Metallurgical Structure. 2. The AISI numbering system:namely 200, 300, and 400 Series numbers. 3.

Grade Q345 Imported Tube does not conform to grade S355

Elongation for Q345 is at the bottom end of the specification which is 0.22% while the local manufactured tube is an average is 0.37%. Lastly but importantly the minimum yield of Q345 is 345MPa which is not the same as the minimum yield of grade S355 which is 355MPa. (For thicknesses less than 16mm) How to weld T-1 constructional alloy steelsof the weld is the most frequent cause of unsound welds in alloy steels. An actual weld made to deliberately produce hydrogen-induced cracking by depositing a weld bead on ArcelorMittal USA T-1 steel with a Type E6010 electrode whose coating inherently has a high hydrogen content.

ABS RULE REQUIREMENTS FOR MATERIALS AND WELDING .2002 iii PART 2 Foreword For the 1996 edition, the Rules for Building and Classing Steel Vessels Part 2:Materials and Welding was re-titled Rule Requirements for Materials and Welding Part 2.The purpose of this generic title was to emphasize the common applicability of the material and welding requirements in Q235 Steel Q235A Q235B Q235C Q235D Equivalent,

  • Q235 SteelFeatures and ApplicationsData Sheet and SpecificationQ235 Steel EquivalentQ235 steel is a plain carbon structural steel which is widely used in China, Q235 material in Chinese standard GB/T 700 is divided into 4 quality grades:Q235A, Q235B, Q235C and Q235D; Density of this steel is 7.85 g/cm3, tensile strength is 370-500 MPa; yield strength is 235 MPa (data are for steel bar or steel plate diameter 16mm). Since its mild steel, it is used directly without heat treatment.Q235 vs. Q345 Steel Plate (How to Distinguish) MachineMfgWhen the general strength design is presented, Q345 is used because Q345 is not only strengthened than Q235 but also save 15% to 20% steel compared to Q235 steel. However, for stability control design, Q235 steel is better. The price difference is 3%- 8%. Regarding how to distinguish the steel plate from Q235 and Q345, therere several methods:

    Q345 Steel Properties. Q345 steel is a Chinese GB standard Low Alloy High Strength Structural Steel, material density is 7.85 g/cm3, tensile strength is 470-630 Mpa, and yield strength is 345 MPa, it has better properties than Q235.According to GB/T 1591 2008, Q345 material has 5 quality grades:Q345A, Q345B, Q345C, Q345D and Q345E. Q345 steel has good weldability, cold & hot workability Q345 steel property and specification are equivalent to To some extent, the Q345 possesses the same property and composition of ASME A572, namely the Q345 is equivalent to A572. This specification covers the standard requirements for Grades 42, 50, 55, 60, and 65 of high-strength low-alloy structural steel shapes, plates and sheet for applications in bolted, welded, and riveted structures in bridges

    STEEL SOME COMMON TYPES

    1018 is a popular carburizing grade of steel. It can be strengthened by cold work ing or surface hardened by carburizing or cyaniding. It is relatively soft and has good weldability and formability. 1020 is a general-purpose low-carbon mild steel. It is easy to fabri-cate by the usual methods such as mild cold or hot forming and welding.
