Steel is one of the most important structural metals.She has found wide application in construction, engineering, as well as many other industries.This metal a lot of different brands, and they are all different from each other characteristics.40X Steel - Structural alloyed grade of this material.Here we'll talk about it more.
Besides the usual impurities, brand 40X contains a certain number of elements that are specifically introduced.This guarantees special properties.Here, as an alloying element chromium is used.It is because of his marking was the presence of the letter H.
This steel has a feature - it's hard weldability.Therefore 40X steel during welding is heated to 300 ° C, and after it - heat treatment.In addition to this feature, there is a tendency to temper the ability and even flokenochuvstvietlnost.
Steel 40X has the following characteristics:
- relative elongation - 13-17%;
- toughness - to 800 kJ / m².meter;
- tensile strength - up to 900 MPa.
There are other features that are typical for this grade of steel:
- endurance limit high enough;
- the ability to carry out the processing method of cutting, welding or by pressure;
- resistance to warping and decarburized at-heat.
For all of these materials are the most important properties.They allow the use of steel 40X in the engineering industry.
When forging steel of the brand at the beginning of the process temperature is 1250 ° C, and at the end of - 800 ° C.
Very often, this steel is used in the manufacture of upgradable parts which have a high strength.It is products such as plungers, spindles, axles, shafts, rings, pinion shafts, crankshafts and camshafts, bolts, half-axis rails, bushings, foam crowns, mandrels and other necessary details.
40 steel is widely used for the manufacture of taps, drills, files.As you can see, it's all the tools that I have to work at a low speed and the heating temperature is not more than 2000 degrees.These products are rods that have a circular cross-section.They are made in accordance with GOST 5950-2000.
If needed steel, resistant to corrosion, it is necessary to pay attention to the brand 40X13.This stainless corrosion-resistant steel.Corrosion resistance after hardening it gets, because in this case is completely dissolved carbide.Steel 40X13 produced in induction furnaces, and arc open type.The resulting material is perfectly deformed at 850-1100 ° C.And that was not cracking, heating and subsequent cooling should be carried out slowly.
Finally it is worth to recommend to customers.Best of all steel 40X, as well as articles of buying from the manufacturers directly.There is always the cost will be no extra charge, because you "get around" intermediaries.Also, products can be made on the parameters you have ordered.In addition, plants often offer discounts to wholesalers, as well as a guarantee of quality goods.And in the case of marriage, you'll know who to call.
