What type of steel is 52100?
Carbon Alloy Steel
52100 is a Carbon Alloy Steel originally developed in 1905 as a bearing steel for high pressure applications (which is why it is commonly referred to as ball bearing steel) but has since become legendary as a blade steel.
What is the hardness of 52100 steel?
Mechanical properties
| Properties | Metric | Imperial |
|---|---|---|
| Hardness, Brinell | – | – |
| Hardness, Knoop (converted from Rockwell C hardness) | 875 | 875 |
| Hardness, Rockwell C (quenched in oil from 150°C tempered) | 62 | 62 |
| Hardness, Rockwell C (quenched in water from 150°C tempered) | 64 | 64 |
What is the composition of 52100 steel?
52100 is a relatively simple steel with 1% carbon and 1.5% chromium, and small amounts of Mn and Si. 52100 steel has been in use since at least 1905 [1]. It was developed for use in bearings.
Is 52100 good for kitchen knives?
52100 is a great steel for Knives. Its exceptional hardness that doesn’t compromise on toughness, as well as great edge retention all make it a great reliable material for knife making.
Is 52100 steel corrosion resistant?
AISI 52100 is a high carbon tool steel containing low quantities of manganese and chromium to improve hardening. Because of the low chromium levels in 52100 steel, it has very low corrosion resistance compared to other higher chromium tool steels.
Can 52100 be welded?
52100 material is very hard to weld. It can be welded by all of the common welding processes providing the section is preheated and stress relieved after welding. The grade of welding rod to be used depends upon thickness of section, design, service requirements, etc.
What is the tensile strength of 52100 steel?
105,000 psi
E52100
| AISI/SAE 52100 (UNS G52986) | High-Carbon, Chromium Alloy |
|---|---|
| Typical Mechanical Properties (Annealed) | Yield – 85,000 psi Tensile – 105,000 psi Elongation – 17% Reduction Area – 50% BHN at surface – 228 |
Is 52100 a low alloy steel?
52100 is a high carbon low alloy steel with good strength melted as AOD + VAR or VIM + VAR melt type. It has excellent rolling fatigue strength at temperatures up to 400oF. This grade also possessed good machinability in the annealed condition prior to final heat treatment.
How do you heat treat steel bearings?
Heat Treatment of 52100 The typical recommended heat treatment for 52100 is a 1500-1550°F austenitize for 10-30 minutes followed by an oil quench and a temper from 300-500°F [1]. Some knifemakers have recommended a 1475°F austenitize.
How do you weld high carbon steel?
High carbon steel is even more prone to weld cracking than the other two groups of carbon steel. Welding high carbon steel will most likely require very thorough preheating and post-heating processes to avoid this. It could also require special welding filler metals.
What is SAE 52100 used for?
Introduction. SAE 52100 is an alloy steel with high carbon with chromium as an alloying element, which has been widely applied in rolling bearings [1]. The traditional heat treatment process for SAE 52100 steel consists of a quenching process followed by a tempering step at low temperature.
