What is 20MnCr5 material?
20MnCr5 steel is a low alloyed engineering case hardening steel for parts which require core tensile strength of 1000 – 1300 N/mm² and good wearing resistance. It is used in boxes, piston bolts, spindles, camshafts, gears, shafts and other mechanical controlling parts.
What is EN9 used for?
EN9 is used commonly for many general engineering applications. Typical applications include, shafts, axes, knives, bushes, crankshafts, screws, sickles, wood working drills and hammers.
How is hardened steel made?
To make hardened steel, manufacturers heat carbon steel to high temperatures, then subject it to a process called quenching. During quenching, the steel is rapidly cooled in a solution of brine or water. After quenching, the steel is very hard, yet also extremely brittle.
What is the preheating temperature of steel?
Pre- and post-weld heat treatment (PWHT)
| Low alloy steel grade | Recommended pre-heat °C |
|---|---|
| T11 | Min. of 200°C, up to 300°C for thick sections1 |
| T22 | Min. of 250°C, up to 300°C for thick sections1 |
| T23 | Typically 150–250°C. Interpass at ~ 300 –350°C1,2 |
| T24 | For wall thickness > 8 mm min. 100°C3 For wall thickness > 15 mm min. 200°C |
What is EN9 steel?
EN9 is a medium carbon steel grade commonly supplied in the as rolled condition. It can be flame or induction hardened to produce a high surface hardness with excellent wear resistance for a carbon steel grade. EN9 bar is available in full lengths or can be cut to your requirements.
What is en36 steel?
EN36 is a carburising steel grade with very high surface strength with a soft but strong core. The material retains a remarkable degree of toughness. With high tensile strength, EN36 is used in the production of numerous high strength parts including crankshafts in the automotive and aerospace sector.
What is an en36c billet?
EN36 is a 3% nickel, chromium, molybdenum grade. Carburised EN36 gives a hard case with a strong core, whilst retaining a remarkable degree of toughness.We can offer you EN36C Billets / EN36 Billets / from ready stock as well as make to order basis. The quality of material is very good.
Why choose a carburised en36 case?
Carburised EN36 gives a hard case with a strong core, whilst retaining a remarkable degree of toughness.We can offer you EN36C Billets / EN36 Billets / from ready stock as well as make to order basis. The quality of material is very good. If you need sample even that can be provided.
How to soften the en36 for machining?
If it is necessary to soften the EN36 for machining between the carburising and subsequent heat treatment stages, heat to 640-650°C. Soak at this temperature for 1 to 2 hours and cool slowly in the furnace or in air.
