42CrMo4 - Ovako

42CrMo4 is a steel for quenching and tempering, which has a good combination of strength and toughness in the quenched and tempered condition. After the oil quenching, the steel will be through hardened up to ø60 mm bar diameter. The microstructure of larger dimensions is not fully martensite. The steel is applicable to induction hardening.

For intermediate grades, the difference between the specified minimum tensile strength and minimum yield strength for the pipe body shall be as given in the table for the next higher grade. b. For intermediate grades, the specified minimum tensile strength for the weld seam shall be the same value as was

Carbon Equivalent Limitation for Weldability of Steels May 25, 2010 · Pcm is more appropriate than conventional carbon equivalent (Ceq) for steels, such as low carbon steels, HSLA (high strength low alloy steels) or TMCP (thermo mechanical controlled process steels). Pcm carbon equivalent formula was developed for steels with low carbon contents (<0.10%) and with tensile strengths of 60 to 130 ksi in Japan.

EN10225 S355G8+M Offshore Steel Plates

EN10225 S355G8+M is a weldable structural steel for offshore structures. We hold a large stock of it together with stocks of other TMCP steels for offshore use, including S355G10+M. Unlike many of the lower EN10225 steels S355G8+M is thermomechanically rolled and quite different to the EN10025 steels due to the addition of Nickel, Chromium and Molybdenum for the corrosion resistant properties.

How to calculate the carbon equivalent? WORLD IRON&STEEL

Mar 08, 2021 · Firstly we should be clear about the difference between carbon equivalent and carbon content. Carbon content is the main factor that determines strength and weldability in carbon steels. With the increase of carbon content, the quenching tendency increases, and the plasticity decreases, which tends to produce welding cracks. NORSOK STANDARDCEV max 0,39 TENSILE TESTING/ IMPACT TESTING The Charpy V-value to be min 50 J EXTENT OF TESTING DIMENSIONS / TOLERANCES NON DESTRUCTIVE TESTING (NDT) SURFACE PROTECTION The surface of the material shall comply to Rustgrade A or B or better according to ISO 8501-1. MARKING CERTIFICATE EN 10 204 Type 3.1B What is a Mill Test Certificate (EN 10204 2.1, 3.1, 3.2)?Sep 28, 2017 · A Mill Test Certificate (MTC), or Mill Test Report (MTR), is issued by a manufacturer to certify the chemical and mechanical features of a product and its compliance to the applicable norms and technical specifications. Typically, Mill Test Certificates conform to the EN 10204 standard and are related to steel products.

Carbon equivalent formulae in relation to hydrogen

For carbon steels, the values deviate from this relationship as the P cm overestimates the cold cracking susceptibility. Where the carbon content exceeds 0.17 wt%, there is a better correlation between CEN and CE IIW:CEN = CE IIW + 0.012 (C 0.17%) Yurioka [8] grouped a number of carbon equivalents for the assessment of weldability, as follows:
