What is bearing quality steel?
Table of Contents
BEARING QUALITY refers to manufacturing restrictions that are employed, when the mill makes the steel. It is commonly referred to as “Clean Steel Production”. The processing refines the steel, removing non-metallic inclusions and generally improving the quality and core integrity of the steel.
What is Cronidur 30 steel?
Cronidur® 30 is a high-nitrogen martensitic cold-work tool steel with exceptional corrosion resistance and ductility at hardness values >58 HRC. Nitrogen is alloyed above its sol- ubility level at ambient pressure by means of the Pressure Electroslag Remelting (PESR) process.
What is bearing hardness?
The typical surface hardness for bearing components made from this material ranges from 60- 64 on the Rockwell hardness C scale (Rc).
What is LC200N steel?
Here is the datasheet for LC200N, which is a European steel made by ZAPP. It was originally designed for use as ball bearing steel for NASA and as a cutting steel in the food, chemical and pharmaceutical industries where its corrosion resistance was needed to counter moisture present in these environments.
Is LC200N better than H1?
H1 is softer steel compared to LC200N and this gives LC200N better edge retention. H1 has poor edge stability and gets dull pretty quickly when put to hard use. H1 outshines Lc200N with higher toughness and holds up well to tough use.
What is the hardness of P20 steel?
P20 is typically sold in the pre-hardened condition at a hardness of approximately 300 HBW.
How hard is bearing steel?
The most common material for ball bearing, roller bearing, and tapered roller bearing is chrome SAE 52100 bearing steel. This bearing can be made by high carbon content of 1.5% and has Rockwell hardness of about 64 HRC.
What is SAE 52100 steel?
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.
How hard is LC200N?
LC200N changes the formula of the steel and now gets quite hard. Data sheets recommend a hardness of 60 HRc, which compares favorably to stuff like 154CM, VG10, and S35Vn. Proof is in the pudding—the Spydiechef sports one of the thinnest, sliceiest blades on the planet, something H1 could never hope to achieve.
How is LC200N made?
It was developed as a bearing steel using a specialized production process (pressurized electroslag remelting), to increase the nitrogen content of the steel through high pressure. The steel has excellent corrosion resistance and toughness as well. This gives LC200N a very good combination of properties.
