1. **EN 10269 Material:**
This European Standard specifies requirements for **steels and nickel alloys for fasteners** (like bolts, nuts, screws) with specified elevated and/or low temperature properties. It covers various steel types (quenched and tempered, case hardening, precipitation hardening, austenitic stainless) and nickel alloys suitable for components needing strength and reliability across a wide temperature range.
2. **EN S275 Material:**
EN S275 refers to a specific **carbon steel grade** defined within the standard **EN 10025 (Hot rolled products of structural steels)**. Primarily made of iron (Fe), its key components are carbon (C), manganese (Mn), and small amounts of silicon (Si), phosphorus (P), and sulfur (S). It's a widely used general-purpose structural steel known for its good weldability and machinability, with a minimum yield strength of 275 MPa at room temperature. Common qualities include S275JR, S275J0, S275J2.
3. **EN 12163 Material:**
This standard specifies requirements for **copper and copper alloy rod for general purposes**. It covers a wide range of alloys (like Cu-DHP, CuZn37, CuZn39Pb3, CuZn40Pb2) supplied in various shapes (round, square, hexagonal) and conditions (drawn, extruded). These rods are typically used in applications like machining components, forgings, construction, and general engineering where good machinability, conductivity, or corrosion resistance is needed.
4. **EN 10217 Material:**
EN 10217 specifies the technical delivery conditions for **welded steel tubes for pressure purposes**. It covers tubes made from non-alloy and alloy steels designed to convey pressurized fluids (like water, steam, gas, oil). The standard includes various test categories (P195 to P500) defining mechanical properties and chemical composition requirements to ensure safety under pressure.
5. **EN 10139 Material:**
This European Standard specifies requirements for **cold rolled uncoated low carbon steel narrow strip and slit wide coil for cold forming**. Made primarily of iron (Fe) with low carbon (C) content and controlled levels of elements like manganese (Mn), phosphorus (P), and sulfur (S), this material is supplied in thicknesses typically below 3mm. It's specifically produced for applications requiring further cold forming operations, such as stamping, bending, or roll forming.
