INTRODUCTION
ASTM A600 M35 steel is a medium-alloyed high speed tool steel. It is also known as HSSE or HSS-E which is similar to M2, but with 5% cobalt added, which makes better hot hardness and
wear resistance. AISI /ASTM A600 M35 high speed steel is suitable
for heat treatment up to 66 HRC, and also offers excellent cutting
performance and offers excellent cutting performance. AISI high
speed Tool Steel M35 is suitable for broaches, taps, milling,
reamers, hobs, shapers cutters, saws ,etc.
HSS M35 is a conventionally manufactured cobalt alloyed high-speed
steel. The various stages of the manufacturing process are chosen
and controlled so that an end product is obtained with a good
structure in terms of carbide size and distribution. this is a
distinct advantage for the finished tool.
APPLICATIONS
AISI HSS M35 tool steel is usually used in conditions with the demand for high hardness . M35 steel is suitable for cutting tools such as cutting tools including broaches, milling cutters,
reamers, end mills and saw blades. It is also a good quality wear resistant HSS
grade for cold work area. Steel M35 is also suitable for cold work
applications, where exacting demands are imposed on wear resistance. The steel
possesses an admirable combination of wear resistance and toughness and in these
respects superior to the high alloyed cold work steels.

PROCESSING
Forging of ASTM A600 High Speed Tool Steel M35
Pre heat the AISI M35 high speed steel slowly and uniformly to
450-500°C and equalise. Then increase M35 tool steel more quickly
to the forging temperature of 950-1100°C and equalise prior to
forging. Do not allow the forging temperature to drop below 950°C,
if this occurs re heating will be necessary. Always cool the steel
very slowly after forging.
Heat Treatment of AISI M35 High Speed Material
- Soft-annealing 850°C – 900°C / 1560°F – 1650°F, slow cooling 10°C /
18°F/h to 700°C / 1290°F, hardness max 260 Brinell.
- Stress relieving 600°C – 700°C / 1120°F – 1290°F, approx. 2 hours
at temperature, slow cooling to 500°C / 930°F.
- Hardening with preheating in two steps 450°C – 500°C / 840°F –
930°F, 850°C – 900°C / 1560°F – 1650°F and austenitizing at 1050°C – 1220°C / 1920°F – 2230°F. Quenching to about 550°C /
1022°F then cool in air to hand warm
- Tempering at 560°C / 1040°F or higher 2 times for at least 1 hour
at full temperature is recommended.
Machinability of AISI M35 Tool Steel
High Speed tool steel M35 can be worked in the same way as other
high-speed steels by plastic forming, machining, grinding,
electrical discharge machining, welding and polishing. M35 tool
steel is amenable to cold forming. In grinding, local heating of
the surface, which might alter the temper, must be avoided.
Grinding wheel makers can furnish advice on the choice of grinding
wheels. Machining is carried out using carbide or high-speed steel
tools.
