API 5L X70 steel pipe has a minimum yield strength of 70,300 psi or 485 Mpa. The current X70 steel pipe are all controlled micro-alloyed carbon-manganese steels. The micro-alloys elements are mainly Nb, V and Ti, and the total content of micro-alloys does not exceed 0.15%.
EN 10088-2 Mechanical Properties of - Stainless Steel PipeEN 10088-2 Mechanical Properties of Austenitic Stainless Steel. EN 10088-2 is the material standard for stainless steel sheet, plate and strip for general purposes. This article gives the 0.2% and 1.0% proof strength, tensile strength and elongation of the 40 austenitic grades specified. The standard also specifies includes impact properties and resistance to intergranular corrosion acceptance
mechanical properties of the seamless steel pipe, mainly its fracture toughness and its fatigue crack growth resistance. 2. Materials and Experimental Procedures The steel studied was manufactured by the company Vallourec & Sumitomo Tubos do Brasil (VSB) and was provided as seamless steel pipe with nominal outside diameter
Heat-treated steels for line pipe and accessories The Mn-Mo-Nb steel developed by Climax Molybdenum Company has good mechanical properties after quench-and-tempering heat treatment. The IN-787 steel and Ni-Cr-Mo steels are also reported to be used as heat-treated grades.
How chemical elements affect the mechanical properties of Aug 27, 2020 · Carbon, a basic element, has the greatest influence on the properties of steel pipe. The influence of different carbon content on the properties of steel is different according to the content of impurity elements in the steel and the different cooling conditions after rolling. With the increase of carbon content in the steel, the hardness of carbon steel in the hot rolled state increases linearly,
Strength and DuctilityEmbrittlementRecommendations to Minimise EmbrittlementFatigue StrengthThe mechanical properties of 19 structural steels from major industrial areas of the world were investigated before and after galvanizing in a major 4-year research project by the BNF Technology Centre, UK, under the sponsorship of International Lead Zinc Research Organization. Included were steels to Australian Standard 1511 grade A specification, and British Standard 4360 series steels. The published BNF report Galvanizing of structural steels and their weldments ILZRO, 1975, concludes tha(PDF) Mechanical Anisotropy in Steels for PipelinesMany linepipe steels exhibit a variation in mechanical properties as a function of the orientation of the test sample relative to the rolling and transverse directions of the steel plate.
STEEL TUBE AND PIPE HANDBOOKand their tolerances; steel standard contains its chemical compo-sition and mechanical properties for various methods of pipe manufacturing and steel tempers. The third standard of the tech-nical delivery conditions (TDC) sets out all remaining require-ments for pipes testing, acceptance, certificates, packaging, marking, etc.
Stainless Steel Properties Technical Resources BLUCHERIn contrast to the pure chromium steels (ferritic stainless steel), this results in significant changes in the mechanical properties, such as increased workability and ductility, better resistance to thermal stress and improved weldability. The austenitic structure also results
of steel strips need to be adjusted to compensate for the change in mechanical properties between the as-delivered coil and the manufactured pipe (greatly influenced by the type of forming, the grade and the dimensions). Our make-to-order strategy ensures that we meet

T91 / P91 SteelThe T91/ P91 steel is primarily used for superheater and reheater in power plant boiler construction, headers, main steam pipeline, as well as the heating furnace piping in petrochemical industry. Compared to other austenitic alloy steels, it has better thermal conductivity and thermal expansivity.
