●High strength and hardness: tensile strength up to 500-2000MPa (2-8 times that of aluminum), suitable for high load structural components.
●High cutting difficulty: need to use tungsten carbide tools (such as YW1/YW2), cutting speed usually 1/3-1/5 of aluminum.
●Thermal deformation control: low thermal conductivity (about 45W/m・K), need sufficient cooling to prevent workpiece deformation.
●Diverse surface treatment: can improve performance through quenching, carburizing, electroplating, etc.
●Wide welding performance differences: stainless steel requires special welding wire, high strength steel is prone to stress concentration after welding.
●Obvious cost stratification: ordinary carbon steel (such as Q235) has the lowest cost, high-speed steel (such as M2) material cost can be more than 10 times.

✔ Machining parameter differences: 12L14 cutting speed can reach 150m/min (ordinary steel 60-80m/min).
✔ SS410 suffers from severe work hardening, it is recommended to use CBN tools.
✔ Welding attention: 40Cr needs preheating at 200℃ before welding, and tempering after welding to eliminate stress. ✔ SS410 welding is recommended to use ER410 welding wire.
✔ Surface treatment compatibility: 45 steel is suitable for quenching + blackening treatment; 10B21 has surface hardness HRC58-62 after carburizing and quenching.
✔ Odporność na korozję: SS410 > Q235 (po ocynkowaniu) > 1010
✔ Wydajność obróbki: 12L14 > 1022 > 40cr
✔ Kompleksowy koszt: Q235 (najniższy) < 1010 < 1022 < 45 stal < 40cr < SS410
