Steel
| Alloy | Material costs | Manufacturing costs | Tensile strength | Hardness | Description |
|---|---|---|---|---|---|
|
S235JR |
€ |
€€ |
350 – 500 |
102 – 140 |
Unalloyed structural steel and the most commonly used steel grade worldwide. It impresses with its versatility, good machinability and excellent welding properties. |
|
S355J2 |
€ |
€€ |
470 – 630 |
146 – 180 |
Unalloyed structural steel with improved mechanical properties compared to S235JR. Thanks to its higher material quality, it is particularly suitable for turned and milled parts and also impresses with its good welding properties. |
|
11SMn30 |
€ |
€ |
380 – 570 |
112 – 169 |
Free-cutting steel that has been specially optimized for machining processes and is frequently used in the automotive industry. It is characterized by excellent machinability. |
|
11SMnPb37 |
€ |
€ |
380 – 570 |
112 – 169 |
Free-cutting steel that has been specially developed for machining processes and is characterized by excellent machinability. Although the addition of lead means that these are no longer RoHs-compliant, they are easier to machine than 11SMn30. |
|
C45 |
€€ |
€€€ |
550 – 700 |
190 (13 HRC) |
Unalloyed heat-treated steel with a uniform material structure that ensures high dimensional accuracy and strength. The material is hardenable and is characterized by its wear resistance. |
|
C60E |
€€€ |
€€€ |
800 – 950 |
270 (28 HRC) |
Unalloyed quenched and tempered steel that impresses with its high strength and good toughness in the hardened and tempered condition. The material is hardenable and wear-resistant, making it ideal for high-performance applications. |
|
16MnCr5 16MnCrS5 |
€€€ |
€€€ |
780 – 1080 |
210 (16 HRC) |
Versatile case-hardening steel that impresses with its high surface hardness and good core strength after case-hardening. The material is easy to machine, weld and harden, making it ideal for numerous applications. |
|
42CrMo4 42CrMoS4 |
€€€€ |
€€€€ |
1000 – 1200 |
220 (19 HRC) |
Alloyed heat-treated steel that is particularly suitable for parts that have to withstand higher mechanical loads than C45 or 16MnCrS5. It is characterized by its hardenability and very high strength. |
|
11SMnPb30 |
€ |
€ |
380 – 570 |
112 – 169 |
Lead-alloyed free-cutting steel with very good machinability, good surface quality and low tool wear at high cutting speeds. Not RoHS-compliant due to its lead content. |
|
30CrNiMo8 |
€€€€€ |
€€€€ |
1250 – 1450 |
340 |
High-strength alloy quenched-and-tempered steel with high through-hardening and toughness, even in large cross-sections. Hardenable and particularly suitable for heavily loaded machine parts such as shafts and gears. |
