Hardox\u00ae 400<\/span><\/span><\/h1>[vc_column_text animation_delay=”0″]\n

The resistance of steel to wear and abrasion is evident throughout the thickness.<\/span><\/h4>\n

Abrasion-resistant Hardox\u00ae 400 steel with a nominal hardness of 400 Brinell units. The wear resistance of Hardox\u00ae 400 steel is evident throughout its thickness.<\/span><\/p>\n

Such a combination of high strength with good bendability and weldability makes it possible to manufacture from this steel constructions subject to moderate wear.[\/vc_column_text][vc_empty_space]<\/span><\/span><\/span>Go to order or inquire<\/span><\/a>[vc_empty_space][vc_row_inner element_id=”310228″ el_id=”button_feedback_product_page”][vc_column_inner]<\/span><\/span><\/span>ORDER A CONSULTATION<\/span><\/a><\/span><\/span><\/span><\/span>GET THE FULL PRICE LIST<\/span><\/a>[\/vc_column_inner][\/vc_row_inner][vc_empty_space][\/vc_column][vc_column animation_delay=”0″ shadow=”true” width=”1\/3″ element_id=”641565″ crp=”480:i:i,480-768:i:i,768-1024:i:i,1024-1280:i:i,1280-1366:i:i,1366-1600:i:i,1600-1920:i:i” css=”.vc_custom_1665361408387{background-image: url(https:\/\/www.hardsteel.com.ua\/wp-content\/uploads\/2022\/10\/380×360-hardox-400.jpg?id=18595) !important;background-position: center !important;background-repeat: no-repeat !important;background-size: cover !important;}”][\/vc_column][\/vc_row][vc_row][vc_column][vc_empty_space height=”52px”][\/vc_column][\/vc_row][vc_row][vc_column]

1) Brinell hardness (HBW) according to EN ISO 6506-1 on a surface milled 0.5 – 3 mm deep. At least one test sample from each melt and for every 40 tons. Deviations of the nominal thickness of the rolled sheet upon delivery from the thickness of the control sample, with which the hardness tests are carried out, do not exceed +\/- 15 mm. For sheet, the Brinell hardness is determined in accordance with EN ISO 6506-1 on each individual heat treatment per roll. Hardness is measured on the milled surface 0.3 – 2 mm below the surface.<\/p>\n

Hardox steel is hardened throughout its thickness. The hardness in the center is at least 90% of the guaranteed surface hardness.[\/vc_column_text][vc_column_text animation_delay=”0″]\n

Tolerances<\/h6><\/span><\/div>
[vc_column_text animation_delay=”0″]\n

Thickness<\/span><\/h3>\n

Thickness tolerances correspond to the guaranteed parameters of Hardox\u00ae steel. The guaranteed parameters of the Hardox\u00ae steel wide sheets meet the requirements of the EN 10 029 class A standard, and the rolled products meet \u00bd the requirements of the EN 10 051 standard.<\/p>\n

 <\/p>\n

Length and width<\/span><\/h3>\n

According to the SSAB range. Tolerances for flat sheets meet the standards of the SSAB company for sheets with uncut edges, which in turn meet the requirements of the EN 10029 standard. Tolerances for coils meet the requirements of the EN 10051 standard. Products with tighter tolerances can be supplied on request.<\/p>\n

 <\/p>\n

Form<\/span><\/h3>\n

The tolerances of broad-sheet products meet the requirements of the EN 10029 standard, and of the rolled products of the EN 10051 standard.<\/p>\n

 <\/p>\n

Flatness<\/span><\/h3>\n

Flat flatness tolerances correspond to the guaranteed parameters of Hardox\u00ae steel according to class D, which exceed the requirements of the EN 10 029 standard. Flatness tolerances of coiled products correspond to the guaranteed parameters of Hardox\u00ae steel according to class A, which are stricter than the tolerances according to the EN 10 standard.<\/p>\n

 <\/p>\n

Surface quality<\/span><\/h3>\n

In accordance with the requirements of the EN 10 163-2 standard for class A, subclass 1.<\/p>\n

Flexible
\n<\/span><\/h3>\n

Flexible properties of wide-rolled steel correspond to the guaranteed parameters of Hardox\u00ae steel when bent according to class E. Flexible properties of rolled products correspond to guaranteed parameters of Hardox\u00ae steel when bent according to class A.[\/vc_column_text]<\/div>
