Hardox Steel

Hardox steel is produced by hot rolling with hardening and tempering, which significantly increases the wear resistance of the material . It acquires increased strength and hardness , due to which it is able to withstand high mechanical loads and operational wear . At the same time, the declared properties are preserved not only on the surface of the sheet , but also manifest themselves throughout the entire structure of the metal .

Practical tests of this grade of steel have shown that products from this range will last 5 (!) times longer than other steel analogues . At the same time, in our company’s catalog you can buy wear-resistant material of the category corresponding to the type of wear – Hardox 400, 450 or 500 steel (Brinell hardness index).

Advantages

• High-strength steel Hardox does not crack even under extreme mechanical impact. This allows using such structural rolled metal products in extreme conditions.
• Abrasion resistance, as well as resistance to impact and abrasion.
• Hardox is good for welding work, after which the work areas are easy to process .
• Convenient sheet form. Hardox metal sheet is used in bending, it is easy to cut blanks from it by any technological methods.

The price of Hardox steel, taking into account its operational advantages, allows you to buy high- quality metal products with a long service life, saving money in the future for other purposes.

Hardox steel range

Steel grade	Brinell Hardness HB	Impact strength KVJ at -400C	Yield strength	Tensile strength Rm	Thickness range mm	Carbon equivalent per 20mm thickness
HARDOX 400	370 – 430	45	1000 N/mm2	1250 N/mm2	4 – 130	0.38

HARDOX 450  was originally developed for truck bodies. This steel has increased hardness (and therefore resistance to abrasion) while maintaining high viscosity and excellent weldability. Today, HARDOX 450 is increasingly used for other purposes.

Steel grade	Brinell Hardness HB	Impact strength KVJ at -400C	Yield strength	Tensile strength Rm	Thickness range mm	Carbon equivalent per 20mm thickness
HARDOX 450	425 – 475	35	1200 N/mm2	1400 N/mm2	3.2 — 80	0.47

HARDOX 500  is particularly used where very high service life is required under abrasion resistance conditions or when working with very hard rocks or minerals.

Steel grade	Brinell Hardness HB	Impact strength KVJ at -400C	Yield strength	Tensile strength Rm	Thickness range mm	Carbon equivalent per 20mm thickness
HARDOX 550	470 – 540	30	1300 N/mm	1550 N/mm2	4 – 80	0.62
	525 – 575	30	140 N/mm	1700 N/mm2	10 – 50	0.72

HARDOX 600  provides extreme hardness with high viscosity. HARDOX 600 competes with materials such as steel castings, manganese cast irons, guaranteeing better accessibility and ease of processing than the above materials.

Steel grade	Brinell Hardness HB	Impact strength KVJ at -400C	Thickness range mm	Carbon equivalent per 20mm thickness
HARDOX 600	570 – 640	20	8 – 50	0.73

When using HARDOX 600 steel, the final values ​​of mechanical properties and the thicknesses produced will be specified. The above-mentioned values ​​of impact toughness KV and hydrocarbon equivalent Ce are given only as typical values.

Technical specifications

Purchasing Hardox steel for use in the production process will significantly optimize scheduled operations. In particular, it will significantly reduce equipment repair costs, as well as the frequency of its maintenance.

An additional property of this metal is its increased impact toughness, so various structures based on Hardox become immune to vibration, impact, shock or friction.

It is rational to buy this material at an affordable price due to the possibility of reducing the final weight of the product. Products and tools made of this steel will have the strength required by technology, but with a reduced weight.

Hardening of the metal is performed over the entire area of ​​the sheet , due to which additional heat treatment of manufactured blanks or final parts is not required.

Design features

The SSAB product range marking defines tolerances for sheet dimensional parameters . The width and length standard EN 10029 – 1991 applies to this grade. If the metal product is manufactured in rolled form, its sale is regulated by EN 10051.

The thickness is also determined by current regulations, according to which possible tolerances are established over the entire area of ​​the sheet .

Scope of application

Taking into account the above parameters and reasonable cost, Hardox 400 can be purchased to solve any important tasks. This material is most in demand in conditions of extreme and intensive use. The mechanical properties of the sheet , depending on the category (by hardness), guarantee the durability of the manufactured products – parts, tools, metal structures.

The “pioneers” of using this rolled steel were industries with high production loads, where the price of raw materials is not a determining factor. These areas include the mining and oil refining industries.

Afterwards, the material became popular in machine-building and machine-tool enterprises. The use of Hardox allowed the creation of equipment with an ideal price -quality ratio. High-strength and wear-resistant excavator buckets, bulldozer blades, mine shovels and other parts used in extreme conditions are made from this steel range. Hardox is also preferred in most lifting machines and mechanisms , which is capable of withstanding extreme loads without cracking. For example, in loading buckets, elements of crane or telescopic equipment.

Today, buying Hardox is also profitable for the construction industry, where a wide range of products for the construction of complex, multi-tiered objects are produced from sheet metal. In this area, the properties of resistance to abrasion and the effects of abrasive substances are most often in demand.

Recently, agricultural machinery manufacturers have also begun to use more “hardox” rolled metal. Mainly in those modules that are subject to maximum wear when in contact with soil, plants, and stones.

The popularity of this steel grade is so high that cheaper analogues with similar properties have begun to appear. But the most competitive offers are characterized by the percentage possession of the same advantages as Hardox . To confirm the compliance of the offered products, the company “StalSnabKomplekt” provides approved certificates.
