Special engineering steel and angle sections
A machine component and a structural support require different material decisions. BVM outlines the information buyers should prepare for special engineering steels and angle sections.
Special steel: specify performance and delivery condition
“Special steel” is a commercial category, not a complete grade specification. State the component, approved technical requirements, full grade and standard, stock form, dimensions, delivery condition and required inspections. Forged parts and tool or mould steel require their own drawing and acceptance requirements. Ovako describes 42CrMo4 as a quenching-and-tempering steel with a combination of strength and toughness after treatment. Its properties depend on the variant, dimensions and condition; this example does not confirm BVM stock.
Angle steel: separate shape from grade
L-sections may have equal or unequal legs. Specify both leg dimensions, thickness and bar length. Channels, I-sections and H-sections are different shapes. ArcelorMittal distinguishes EN 10056-1 dimensions, EN 10056-2 tolerances and material grade standards. An L-section size alone does not establish the steel grade. For frames, bracing or supports, follow the approved design rather than selecting by appearance.
A clear enquiry and receiving checklist
Provide the drawing or application, grade and standard, dimensions, quantity, surface condition, certificates and delivery schedule. Add machining, heat treatment or coating requirements where applicable. Match labels and heat identification to the certificate and check dimensions, straightness and surface against the agreed acceptance criteria.
