Alloy Machinery Steel Spheroidized anneal Seamless Steel Tube GB
GCR15/EN31/AISI52100/SUJ2
Product Introduction
Alloy 52100 bearing quality / aircraft quality dual certified steel
is a moderately deep hardening alloy having high resistance to
wear, medium toughness, and low resistance to softening at high
temperatures. It is an oil hardening high Carbon - Chromium alloy
that develops high surface hardening.
52100 Premium Quality VAR is 52100 melted twice (vacuum arc
remelted) and is used in various bearing applications for aircraft
or other critical parts. It has excellent wear and abrasion
resistant qualities and can also be used in place of tool steels.
It has the same basic properties as 52100 but the VAR melting
provides extreme cleanliness.
EN31 is a very high strength steel alloy which is hardened and
tempered before supplying and has nickel, chromium, molybdenum
making it high tensile steel strength, with good ductility and wear
resistance. With relatively good impact properties at low
temperatures, EN31 is also suitable for a variety of elevated
temperature applications. EN31 round bars have good internal
strength and high external strength, which makes it highly wear
resistant. EN31 steel round bars offer good combination of
ductility, strength and wear resistance. EN31 is a very high
strength alloy engineering steel.
Advantages/Features
Superior hardness, 60-67 on Rockwell hardness scale (Rc) at room
temperature
High carbon chrome alloy steel
Operates continually at temperatures up to 120°C
Used to produce precision ball bearings and roller bearings
Cost-effective
Long working life
