BHN - Brinell Hardness Number - Engineering ToolBox

BHN = 2 P / ( D (D - (D2 - d2)1/2)) (1) where. BHN = Brinell Hardness Number. P = load on the indenting tool (kg) D = diameter of steel ball (mm) d = measure diameter at the rim of the impression (mm) It is desirable that the test load are limited to a impression diameter in the range of 2.5 to 4.75 mm.

Carbon Steel Handbook - OLI

weldability, carbon steel is one of the most commonly used materials in the electric power generation industry. Carbon steels in which carbon represents 0.150.35%those used most often as boiler and piping materialsare the focus of this Carbon Steel Handbook. Although carbon steel is available in virtually all product forms, it is the IS 3074 (2005):Steel Tubes for Automotive Purposesof steel tubes (first revision) Dimensions for steel tubes for automotive purposes (first revision) Hot-rolled steel strip for welded tubes and pipes - Specification (second revision) IS No. Tubes shall be free from loose rust, scale and other harmful defects. Ends of tubes shall be cut square, if required by the purchaser. 6 STRAIGHTNESS Kovar Tech Data - High Temp Metals

  • DescriptionApplicationsmagneticpropertiesThermalExpansion PropertiesPreparationfor SealingWorkabilityTypicalmechanical PropertiesKovar alloy is a vacuum melted,iron-nickel-cobalt, low expansion alloy whose chemical composition iscontrolled within narrow limits to assure precise uniform thermalexpansion properties. Extensive quality controls are employed in themanufacture of this alloy to ensure uniform physical and mechanicalproperties for ease in deep drawing, stamping and machining.MuMetal Shielding Performance - MuMETAL® High By use of the B-H curve, our MuMETAL shielding has been developed and refined to offer the most effective shielding characteristics for a variety of applications and markets. The B-H curve depicts our material capabilities to attenuate and shield a wide range of magnetic fields.

    Material Properties of S355 Steel - An Overview

    Aug 23, 2015 · Material Properties of S355 Steel - An Overview. S355 is a non-alloy European standard (EN 10025-2) structural steel, most commonly used after S235 where more strength is needed. It got great weldability and machinability, let us see more mechanical details of this steel. Microstructure and Mechanical Properties of Dissimilar May 09, 2017 · In the present study, St37 low-carbon steel and 304 stainless steel were welded successfully, with the thickness of 2 mm, by a friction stir spot welding process carried out at the tool dwell time of 6 s and two different tool rotational speeds of 630 and 1250 rpm. Metallographic examinations revealed four different zones including SZ and HAZ areas of St37 steel and SZ and Nanocrystalline soft magnetic material FINEMETSi-steel Examples of DC B-H curve cut c meta 1.23 1.20 0.50 0.48 2.5 2.7 3,500 7.5 570 ~ 0 1.2 7.3X10 3 Common Mode Chokes H for *EMI filters Com Saturation flux density Bs (T) Thickness:~18 µm grain size:~10nm Rapidly quenched amorphous phase Amorphous metal ribbon Ribbon winding
