- 06 SteelsC45 / C45E (Ck45) — 1.0503 / 1.1191The medium-carbon quenched and tempered steel C45 and its variants C45E (formerly Ck45) and C45R: designations and equivalents, chemical composition, strength in the normalized and quenched-and-tempered condition, hardness, heat treatment, weldability and cutting data.
- 06 Steels42CrMo4 — 1.7225The chromium-molybdenum quenched and tempered steel 42CrMo4: designations and equivalents (AISI 4140, SCM440), chemical composition, strength by section size in the quenched and tempered condition, hardness, heat treatment, weldability and machining.
- 06 SteelsS355 (St 52-3) structural steelThe non-alloy structural steel S355 to EN 10025-2: the quality grades JR, J0, J2 and K2, how they relate to the old St 52-3 and St 44-2, chemical composition, yield and tensile strength by thickness, impact energy, weldability — and why "St 52" tube is a different steel.
- 06 Steels16MnCr5 — 1.7131 case-hardening steelThe manganese-chromium case-hardening steel 16MnCr5: designations, chemical composition, hardness in the delivery conditions, carburizing and hardening temperatures, weldability and machining — and why its core strength has no single value.
- 06 Steels304 and 316 stainless steel — 1.4301 / 1.4401The austenitic stainless steels 304 and 316 and their L, Ti and free-machining variants: designations, EN and ASTM composition limits, strength, physical properties, solution annealing and sensitization, pitting resistance, welding, and why they are hard to machine.
- 06 Aluminium and light alloys6061 and 6082 aluminium — EN AW-6061 / EN AW-6082The heat-treatable Al-Mg-Si alloys 6061 and 6082: designations, EN 573-3 composition, tempers from O to T6511, EN 755-2 and EN 485-2 strength, physical properties, solution treatment and ageing, strength loss at welds, anodizing, and machining.
- 06 Aluminium and light alloys7075 aluminium — EN AW-7075 / 3.4365The high-strength Al-Zn-Mg-Cu alloy 7075: designations, EN 573-3 composition, T6, T651, T73 and T7351, plate and bar strength by thickness, physical properties, heat treatment, stress corrosion and the conductivity check, quench stresses and distortion, welding, and machining.
