Abrasion Resistant Steel Sheet

 

Abrasion-resistant steel, also called wear-resistant steel, has increased hardness and toughness compared to conventional high-strength steel, lasting up to 4 times longer - where hardness is the ability to with stand rubbing or scraping and toughness is resilience against fracturing.

 

AR400 versus AR450 versus AR500+

Different mills may have different "recipes" for AR steel, but produced material is administered a hardness test – known as the Brinell Test – to determine the category in which it falls. Brinell tests performed on AR steel materials typically meet ASTM E10 specifications for testing material hardness.

 

The technical difference between AR400, AR450 and AR500 is the Brinell Hardness Number (BHN), which indicates the material's level of hardness. Materials with higher BHNs have greater levels of hardness, while materials with lower BHNs have lower levels of hardness:

• AR400: 360-440 BHN Typically
• AR450: 430-480 BHN Typically
• AR500: 460-544 BHN Typically
• AR600: 570-625 BHN Typically (less common, but available)

Abrasion Resistant (AR) Steel Plate is a high carbon alloy steel specifically designed to have higher hardness properties than mild steel.

 

Abrasion Resistant Steel Plate is a steel plate with a high carbon content, alloyed with a range of different elements such as carbon and boron. Wear-resistant steel plates are typically produced using a hardening process, which increases the hardness of the steel and creates a unique grain structure.

 

Wear is the process by which the surface of a material is abraded by friction. Scratches, abrasions or slow wear occur when a surface comes into contact with different components or materials. This is a common problem in heavy industry, but can also be a problem for machines with long duty cycles or harsh operating conditions. Material lubrication can improve performance, but it is best to use wear-resistant materials.

 

 

1. Construction equipment. Construction equipment, including structural beams, bulldozers, compactors, etc., can benefit from the use of AR steels, as most of this equipment is exposed to highly abrasive media.

 

2. Mining equipment. All tools used in the mining and excavation process need to be resistant to wear, corrosion and impact. The tools, parts and machinery used in this industry often come into contact with heavy metals and highly abrasive materials, so AR steel is not only beneficial, it is a must. It is a must.

 

3. Agricultural tools. Most of the common tools and equipment used in the agricultural industry are lined or made of wear-resistant steel. Since they are often used outdoors, these pieces of equipment directly benefit from the wear resistance provided by AR steel.

 

Abrasion resistant steel plate is mainly divided into three categories: general-purpose, impact-resistant and high-temperature-resistant; the total thickness of wear-resistant steel plate can be as small as 5.5 (2.5+3) mm, and the thickest can be as thick as 30 (15+15) mm; the wear-resistant steel plate can be rolled to produce wear-resistant pipes with the smallest diameter of DN200, and it can be processed to form wear-resistant elbows, wear-resistant tees, and wear-resistant reducers.

 

Abrasion Resistant Steel Applications

Abrasion-resistant steel is typically used in applications where there is a lot of wear and tear, such as in mining equipment, construction equipment, dump bodies, and excavator buckets. AR steel is made by adding certain alloys to the steel during the manufacturing process, which makes it more resistant to abrasion and helps it to last longer in harsh environments. Any industry or application that requires equipment to withstand harsh environments and constant use can benefit from the use of abrasion-resistant steel.

 

Some examples include:

• Mining equipment such as dump truck beds/bodies, buckets, and shovels.
• Construction equipment such as bulldozers, backhoes, cement mixers, and excavators.
• Agriculture equipment such as plows, cultivators, and combine harvesters.
• Oil and gas or drilling equipment such as drill bits and pipes.
• Transportation applications like truck bed liners and railcar liners.

 

 

The most important benefit of any AR steel is in its durability against scuffing, scratching, and wearing. Abrasion-resistant steel is designed to resist wear and tear caused by abrasive materials. All AR is resistant to some degree of impact as well. AR can last longer in high-stress situations and reduce downtime from components failing and replacement. It can improve the longevity of your machinery and maximize production time. The benefits of using abrasion-resistant steel make it popular in harsh conditions.

GNEE STEEL is currently participating in the procurement phase of a 100,000m³ full containment ammonia storage tank project, supplying high-quality steel plates for critical tank components. Due to the corrosive nature of ammonia and the risk of Ammonia Stress Corrosion Cracking (SCC), the project requires strict metallurgical control of materials according to EN 10028-3 standards.

 

One of the most important technical requirements of this project is the strict limitation of the actual Yield Strength (Re) for all NL2 grade materials. To prevent SCC risks in ammonia storage environments, the actual yield strength must not exceed 390 MPa, regardless of the nominal values specified in the standard or plate thickness ranges. This requirement places higher demands on steelmaking process control, heat treatment stability, and material testing.

 

Raw high-strength steel plates ready for the 100,000 m³ full containment ammonia storage tank production

 

Project Materials and Technical Requirements

 

The project mainly uses P355NL2 and P275NL2 normalized pressure vessel steel plates, which are widely applied in low-temperature storage tanks due to their excellent toughness and weldability.

 

Key technical specifications include:

• Material grades: P355NL2 and P275NL2 (Normalized)
• Yield strength: Standard minimum / Maximum limited to 390 MPa
• Hardness: ≤ 225 HBW in base material
• Impact testing: Charpy-V notch test at -50°C, minimum 27J
• Certification: EN 10204 3.1 certificate, with optional 3.2 certification

 

These strict requirements ensure that the steel plates maintain stable mechanical properties and high resistance to ammonia-induced stress corrosion during long-term operation.

 

Precision rolling and forming of steel plates into curved sections for the 100,000 m³ ammonia storage tank.

 

Project Plate Quantities and Thickness Distribution

 

The total steel demand for this ammonia storage tank project is several thousand tons, mainly distributed across different tank sections:

 

P355NL2 – Inner & Outer Tank Shell Plates

• Lower shell courses: 50 mm thickness – approx. 2,000 tons
• Middle shell courses: 25 mm thickness – approx. 1,400 tons
• Upper shell courses: 10 mm thickness – approx. 500 tons

 

P275NL2 – Tank Bottom Plates

• Thickness: 10–15 mm – approx. 750 tons

 

P275NL2 – Suspended Roof Structure

• Thickness: 5–8 mm – approx. 180 tons

 

S275JR – Outer Roof (Ambient Structure)

• Thickness: 10 mm – approx. 450 tons

 

To improve tank fabrication efficiency and reduce circumferential welds, the project also requires wide steel plates to minimize welding joints, which helps reduce the potential risk of SCC in ammonia service conditions.

 

Formed steel segments wrapped and racked for protection, ready for 100,000 m³ ammonia storage tank assembly.
