High-quality engineering steel

High-quality and engineering steel – steels with a special degree of purity

Quality and engineering steels are high-grade steel alloys that are used in various construction projects and industrial applications due to their special properties. They are characterised by high strength, good weldability and durability. Quality and engineering steels are characterised by higher purity, strength and wear resistance than conventional structural steels. They are often better weldable and more resistant to corrosion and fatigue.

Here you will find our extensive range of quality and engineering steel. Especially for special material requirements, highly complex applications, special dimensions or compliance with certain standards, we are your suitable contact.

HSM^® supplies hight-quality and engineering steels in all technically possible dimensions and delivery forms. Your desired grade is not available as a tube from the factory? Then we will produce a tube for you from the bar in exactly the dimension you require.

As a system supplier, we can also provide you directly with all services relating to the procurement of your material.

Pressure vessel steel

High compressive strength at all temperatures

Pressure vessel steels are special steels developed for the construction of pressure vessels and other high-pressure applications. These steels have special mechanical properties that enable them to withstand high pressures and temperatures.

Pressure vessel steel is characterised by high strength, ductility (deformability), weldability and corrosion resistance. These properties are crucial to ensure the safety and reliability of pressure vessels. Pressure vessel steel can withstand high pressure at different temperatures (very low to very high). This steel is suitable for normalising and stress relieving annealing.

These pressure vessel steels are used in the production of

• Boilers
• Pressure- and steam pipes
• Barrels
• Heat exchanger
• Industrial heat
• Heating vessels

Case hardening steel

Highly resistant steel for case hardening

Case hardening steel is a special type of steel that is used in a variety of applications due to its excellent hardness, wear resistance and toughness. Case hardening steel is characterised by high hardness, good wear resistance and toughness. Therefore, it is often used for the production of tools, moulds and components that are exposed to high loads and wear. Case-hardened steel is used in various industries, including toolmaking, mechanical engineering, automotive, aerospace, and many others.

Case hardening steels have a carbon content of approx. 0.1 – 0.2 % and are unalloyed or low-alloyed. The carbon content and the alloying elements (Cr, Mn, Ni, Mo) favour through-tempering and form a hard surface layer, which makes the material particularly wear-resistant and tough at the same time.

Depending on the field of application, we are happy to supply you with a wide variety of delivery forms (tubes, special profiles, sectional tubes, etc.) in accordance with EN, ASME, ASTM, AISI, UNS, … etc.

Nitriding steel

Tempering steel for extreme mechanical stress

Nitriding steels are steel alloys specially developed for nitriding. This process increases the hardness, wear resistance and corrosion resistance of the steel, making it suitable for applications in the automotive industry, aerospace, power generation and many other industries.

Nitriding steel belongs to the quenched and tempered steels and is alloyed with various elements (Cr, Mo, Al). This material is produced through many processing steps and is characterised by special properties:

• very high surface hardness
• very high wear resistance
• temper resistance up to 500°C
• high toughness in it’s core
• corrosion resistance

Nitriding steels are used in all areas with extreme loads, especially in mechanical engineering, e.g. control cams, rod pressing tools, piston pins, precision measuring devices, etc.

The material is available in round, flat, square, sheet, cut to size and more. As your steel and metal supplier, HSM^® will provide you with your nitriding steel requirements quickly and flexibly.

Tempering steel

Material with high tensile and fatigue strength

Tempered steel is a stainless steel that is given a high tensile and fatigue strength by quenching and tempering. This steel alloy has been specially treated to increase its strength and hardness. This manufacturing process is called tempering . In this process, the steel is heated to a critical temperature and then rapidly cooled in a medium such as water, oil or air.

This material is characterised in particular by their toughness, which is significantly influenced by the ratio of hardness and tempering temperature. The carbon content of quenched and tempered steels is between approx. 0.2 – 0.6 %; in addition, different alloying elements (Cr, Mn, Mo, Ni) are added depending on the intended use. Tempered steel has a high resistance to mechanical stress and thermal stress.

This material is used in mechanical engineering and toolmaking for the manufacture of

• Crankshaft and gear shaft
• Axes
• Bolts
• Screws
• Connecting rods
• and others

Rolling bearing steel

Hard-wearing working steel

Rolling bearing steel is a special high-quality steel used for the manufacture of rolling bearings. This steel alloy has special properties that make it particularly suitable for use in rolling bearings. Rolling bearing steel is characterised by high hardness, strength, wear resistance and good surface quality. These properties are crucial for low-friction rolling and sliding in rolling bearings.

There are different types of rolling bearing steel

• Chrome steel (also known as 52100 steel/1.2057)
• Stainless steel
• Ceramic steel
• Plastic steel

Each of these steels has its own specific properties, which can vary depending on the application. Due to these good properties, the steel alloy is used in the rolling bearing industry and is used to manufacture rolling heads, guide rails, spacers, shafts, gears, ball bearings or similar.

The most important areas of application

• Machinery
• Automobiles
• Aircraft and other means of transport
• Forging, rolling and machining industry

HSM^® procures various delivery forms from flat to round in your desired dimensions.

Heat resistant steel

Resistant up to 600°C

Heat-resistant steel is a special steel alloy developed for use at high temperatures. These steels retain their strength and other mechanical properties at temperatures far above those of normal steels.

Heat-resistant steels are used in various industrial applications, especially in areas where high temperatures occur: such as power plants, chemical plants, oil refineries, steam generators, furnace construction and other high-temperature environments.

Heat-resistant steels are characterised by extreme resistance at very high temperatures. The operating temperatures can be between 400°C and 600°C, and at particularly high temperatures they are also referred to as high-temperature steels. The strength properties of these steel alloys increase with increasing heat, which ensures good mechanical stress.

Heat-resistant steels are used, among other things, for screws, steam pipes, large forgings, turbine shafts and screws. Enquire directly about your requirements – HSM^® will be happy to send you a non-binding offer.
