Hardox® HiAce—durability that pays off
What’s eating your steel?
When your equipment operates in corrosive or wet environments, failure isn't a question of if —it's when. Corrosive wear doesn’t just damage steel—it accelerates mechanical wear, attacking standard AR steel from the outside in. The result? Unexpected downtime, higher maintenance costs, and reduced productivity. Other materials like stainless steel can resist corrosion—but when corrosion and wear act together, Hardox® HiAce is the toughest corrosion-resistant metal. This latest addition to the powerful Hardox® wear plate family is specifically developed for aggressive applications in industries that face both abrasive and corrosive threats, including municipal and industrial waste management, recycling, wood processing, pulp and paper, waste-to-energy plants, in mining and process industries as well as agriculture and forestry.
A silent and costly intruder
While wear is often obvious, corrosion is stealthy—slow, hidden, and just as destructive. Left unchecked, it leads to accelerated wear, costly failures, eroded budgets, and lost confidence in your equipment. Hardox® HiAce offers superior resistance to corrosive wear and delivers longer service life where other steels fall short.

Built for industries that wear other steels down
In the most punishing environments, steel equipment faces constant attack—from acids, humidity, sulfates, chlorides, ammonia, and other aggressive substances. Household waste, wood chips, manure, potash, and other by-products of industrial processes all pose unique chemical challenges that accelerate corrosion and wear. Hardox® HiAce has a specialized composition that resists corrosive wear in diverse environments. In agriculture, it stands up to ammonia exposure and sulfur-rich fertilizers. In pulp and paper operations, it resists acidic conditions created by chemicals and moisture. And in mining, it performs in the presence of iron ore, chloride-laden copper, bauxite, coal, or other corrosive materials. Whatever the challenge, Hardox® HiAce endures where conventional steels break down.
Waste and recycling: Where corrosion and acids rule
Corrosion eats steel. Hardox® HiAce fights back.
In waste management and recycling, garbage trucks, containers, tippers, grapples, and plant equipment face relentless exposure to corrosive and abrasive materials. Municipal waste and biomass accelerate wear, quickly breaking down standard AR steel. Hardox® HiAce is specifically engineered for this environment—resisting both corrosion and mechanical abrasion to extend equipment life, reduce unplanned maintenance, and deliver dependable long-term performance.
> Ideal for wet, corrosive processes and aggressive handling
Wood, pulp and paper: Daily grind of abrasion and moisture
Wet bark, wood chips, and acidic by-products? No match for Hardox® HiAce.
In pulp and paper mills, equipment faces constant exposure to wet bark, wood chips, and acidic by-products. Unlike conventional steel, which wears down quickly, Hardox® HiAce is engineered for these demanding conditions— delivering superior abrasion resistance and corrosion protection where conventional steel fails. From log and screw conveyors to wood processing equipment, it stands up to both high moisture and chemicals, extending service life, reducing maintenance, and keeping productivity flowing.

Success stories: Hardox® HiAce in action around the world
“Designing the container with Hardox® HiAce makes it stronger even with thinner plate.”
— Keita Shirakawa, Shirakawa Tekko Corp
Lower weight, less welding, and containers that last up to 2.7 times longer. That’s what Shirakawa Tekko gained when they started building waste containers with Hardox® HiAce steel. As one of Japan’s biggest hooklift container manufacturers, they understand the impact that thinner, lighter, and more durable steel plates can have on payload, fuel efficiency, and reduced emissions.
“Since we switched to Hardox® HiAce in our wood conveyor two years ago, we haven’t noticed any wear so far.”
— Rolf Ebbvick, Trosa Energi
At this biomass power plant in the tiny town of Trosa, Sweden, wood chips with 60% moisture content posed a tough challenge for the critical equipment used in a long energy chain. In the company’s new loading bay, Hardox® HiAce successfully fights a combination of acidic corrosion and moisture that would otherwise eat away at the log conveyor and cause premature wear.
“Using Hardox® HiAce was a first for us, and a positive surprise. No changes to our machines or extra training were needed.”
— Volker Stammer, Metallbau Perger
Metallbau Perger GmbH & Co. KG recently introduced Hardox® HiAce wear plate to protect high-wear areas. The plant’s grapple, used to handle biomass from the receiving bay to storage, was upgraded with Hardox® HiAce. The storage area, where moisture is added for combustion control, is now also lined with it, ensuring lasting performance under tough conditions.
