BS ENAlloy Steel
is a common chromium-molybdenum steel that usually used after quenched
and tempered, with high intensity, high hardenability. BS EN 42CrMo4
round steel has better performance than 34CrMo4 steel due to the carbon
and chromium content is higher.
has higher strength and hardenability. The 42CrMo4 alloy material also
has high fatigue strength and good low-temperature impact toughness. The
temper brittleness is not obvious.
Although 42CrMo4 steel is more expensive than 41Cr4 steel, it is more
preferable in terms of material properties. EN 42CrMo4 alloy
engineering steel materials have been widely used in automotive driving
elements. Otai Steel is able to supply you prime quality of 42CrMo4
alloy steel materials with wide range.

5. Heat Treatment of 42CrMo4 Steels
Annealing of 42CrMo4 Steels
Heat steel 42CrMo4 forged steel slowly and thoroughly to 800-850°C;
Cool slowly in the furnace to the temperature 480°;
Complete annealing the steel in the air.
Quenched and Tempered (Q+T)
Heat 42CrMo4 steel slowly to 880°C;
Soak at this temperature then quench in oil;
Temper as soon as 42CrMo4 steel reach room temperature (20°C);
Heat uniformly to the suitable temperature of 560°C;
Withdraw the 42CrMo4 material from the furnace and cool in the air.
6. Forging of 42CrMo4 Alloy Steel
Preheat 42CrMo4 engineering steel uniformly and slowly;
Increase the forging temperature up to 1150-1200°C.
Always keep the forging temperature above at least 850°C
steel 42CrMo4 has only limited weldability. Preheating to 200-300°C is
strongly recommended; the upper limit should not be exceeded because of
risk for deterioration of the chrome layer.
Alloy steel 42CrMo4
can be friction welded. However, precautions are necessary so as to
limit the formation of undesirable microstructures in the welded zone.
8.Application of 42CrMo4 Alloy Steels
42CrMo4 alloy steel is widely used for engineering steel purpose, such
as: making various kinds of machinery, automobile, mining spare part,
the gearwheel of the engine, the driving gear of supercharger, the
connecting rob, the pinchock under the high pressure, parts for power
train applications, cold formed fastener components, shafts, gears,
drill collars for the oil exploration, etc.
Stover Pump Jack Base in 5 pieces was welded by a novice welder.
Muggyweld.com customer Herman Ginger used the 77 arc rod to repair the base with a Miller AC/DC welding machine at 70 amps, and sent us the photos and testimonial of the repair. He tacked the part together and beveled the area to be welded for netter penetration. The 77 arc rods will work on cast iron, cast steel and mild steel in any combination. Some welders use the 77 as a TIG rod without removing the coating.

We start off our adventure into X-Com Long War today, let’s hope that some of us make it out alive in the end! Just a reminder this is my first run at this massive overhaul mod so I’ll be playing on ‘normal’ as that is recommended overall.
Also I’ll probably be going a little slower than normal just since this is all new to me I want to make sure that I understand it so things might be “slow” but that’s just how it’s going to be so I hope you can understand that.
Feel free to leave any tips or suggestions and I’ll look forward to reading them as I look at all my comments. As always don’t forget to leave a comment and like or subscribe if you want to see more!
