Development of coiled steels for electric-welded (HFC) oil Jan 27, 2010 · New steels 06GB (strength classes K48K52) and 07GFB (strength class K55) have been developed for oil and gas line pipe welded with high-frequency current (HFC), while steels 18GFB (strength group K c, y 491 MPa) and 15KhGMF (strength group E c, y 552 MPa) have been created to make pumpcompressor tubing and casing welded with HFC. A technology developed for
Development of controlled rolled high strength Nb and An increasing market need for high strength low alloy (HSLA) strip steels for oil and gas API (American Petroleum Institute) pipelines of superior grades has placed an even increasing pressure upon the steel works for high quality steel strip. In order to achieve this goal as well as to optimize the controlled rolling process of its hot strip mill, COSIPA Steel Co. and the Federal University
JFE Steel has developed a series of high strength, heavy section round steel pipes from tensile strength (TS) class 4 0 N/mm2 to 780 N/mm2 (yield strength (YS) class 385 N/mm2 to 630 N/mm2) which suitable for these special projects, and has confirmed that these products satisfy the performance requirements of building con-struction applications.
High strength microalloyed CMn(VNbTi) and CMn(VNb May 25, 2006 · 1.. IntroductionHigh strength microalloyed steels have been used for the production of welded pipes for more than 30 years. However, the alloy design of pipeline grades is being continuously modified and the process technology optimized because of increasing demand of high strengthtoughness combination requirement of pipeline steels.
High strength steels IndusteelHigh strength steels. Industeel offers a complete range of high strength steel plates including all the main grades commonly found on the market (690, 890, 960 and 1100 MPa). The quenched and tempered steel combines high yield strength and toughness and are used for the construction of stationary and mobile equipment subjected to heavy loads.
In response to the increasing demand to improve both transportation efficiency and performance, the steel pipe industry has conducted extensive efforts to develop line pipe steel grades with superior metallurgical and mechanical (strength, toughness and ductility) properties in order to allow exploitation in hostile environments. This paper aims to give an overview of recent developments of
New developments of advanced high-strength steels for Dec 01, 2018 · Beyond the most conventional ferritic low-alloyed grades used by the automotive industry, several new families of advanced high-strength steels have been developed for cold-forming application, some of them being even industrialized now:the first generation of AHSS, including DP and TRIP steels, the second generation of austenitic TWIP steels, and the third generation of AHSS,
