What is HARDO X450 equivalent grade in India
The equivalent grade of Hardox 450 in India is Abrex 450 (also known as Sumihard 450). Abrex 450 is a wear-resistant steel grade that is manufactured by Nippon Steel & Sumitomo Metal Corporation (NSSMC). It is a kind of high-tensile strength steel with excellent properties in terms of corrosion resistance and weldability. Abrex 450 steel plate is commonly used for heavy-duty applications where a combination of high strength and good wear resistance are important such as for earth-moving machinery, mining and quarrying equipment, materials handling equipment, bulldozers, hydraulic shovels, buckets and other industrial equipment.
Abrex 450 is an abrasion-resistant steel that features a surface hardness of 450HB (HRC 45-50) and the maximum hardness of the wear layer is 5465HV (HV 500-550). It is a medium carbon steel with a nominal 0.45% carbon content and contains manganese, silicon and chromium as alloying elements. The microstructure of the material consists of hard martensite, tempered bainite and soft ferrite. The surface hardness is greater than that of mild steel, boasting more than twice the wear characteristics of common mild steel plates.
Abrex 450 steel plate offers excellent weldability, complete slag removal, minimal spatter and excellent bead retainment, providing a clean acceptance to the base material. It also offers outstanding weldability that can be used with any welding techniques and enables welds to be made without preheating or post-weld heat treatment. The hard wearing properties of Abrex 450 steel allow for increased efficiency of the structures, longer equipment life and reduced maintenance cost. Wear plates in Abrex 450 steel grade can be cut, bent and welded in order to match the shape and dimensions of the intended application.
Abrex 450 steel is used in various applications such as construction, mining and quarrying, forestry and heavy equipment in various parts of the world. This steel grade can be utilized as blades, ditching buckets, demolitions pieces, dump trucks, excavator buckets, forester rotators and skidsteer attachments. This steel grade is particularly popular in the Indian market due to its excellent wear resistant properties and its ability to maintain high tensile strength and good weldability which makes it suitable for many heavy-duty applications.
Overall, Abrex 450 is a high tensile steel grade with excellent wear characteristics and good weldability properties. It is widely used for heavy equipment in various industrial applications due to its remarkable strength, wear resistance and excellent working properties. As a Hardox 450 equivalent grade in India, Abrex 450 is a reliable material for highly demanding applications and is the preferred choice for many industrial applications.
