Steel
| Alloy | Material costs | Manufacturing costs | Tensile strength | Hardness | Description |
|---|---|---|---|---|---|
|
S235JR |
€ |
€€ |
350 – 500 N/mm² |
102 – 140 HB |
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 N/mm² |
146 – 180 HB |
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 N/mm² |
112 – 169 HB |
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 N/mm² |
112 – 169 HB |
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 N/mm² |
190 HB, 190HB (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 N/mm² |
270 HB(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 N/mm² |
210 HB(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 N/mm² |
220 HB (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. |
