布氏硬度HBS和HBW有什么区别?_技术支持

WebJan 27, 2013 · 布氏硬度的符号用 hbs或hbw表示。 hbs表示压头为淬硬钢球，用于测定布氏硬度值在450以下的材料，如软钢、灰铸铁和有色金属等。 hbw表示压头为硬质合金，用于测定布氏硬度值在650以下的材料。 表示方法 布氏硬度的表示方法： hbs或hbw之前的数字为硬度值，后面 ... 1.6 HBS 10/100 Hardwood: 2.6–7.0 HBS 10/100 Lead: 5.0 HB (pure lead; alloyed lead typically can range from 5.0 HB to values in excess of 22.0 HB) Pure Aluminium: 15 HB Copper: 35 HB Hardened AW-6060 Aluminium: 75 HB Mild steel: 120 HB 18–8 (304) stainless steel annealed: 200 HB: Quenched and … See more The Brinell scale /brəˈnɛl/ characterizes the indentation hardness of materials through the scale of penetration of an indenter, loaded on a material test-piece. It is one of several definitions of hardness in materials science See more Proposed by Swedish engineer Johan August Brinell in 1900, it was the first widely used and standardised hardness test in engineering and metallurgy. The large size of … See more When quoting a Brinell hardness number (BHN or more commonly HB), the conditions of the test used to obtain the number must be … See more • Brinelling • Hardness comparison • Knoop hardness test • Leeb rebound hardness test See more The typical test uses a 10 mm (0.39 in) diameter steel ball as an indenter with a 3,000 kgf (29.42 kN; 6,614 lbf) force. For softer materials, a smaller force is used; for harder materials, a tungsten carbide ball is substituted for the steel ball.
