WearCalc™ 2.1 makes tough decisions about choosing the right wear plate easy.

Business can be tough. As your equipment takes a pounding every day, you probably wonder how much wear and tear it can take, if you’ve chosen the right materials and steel grades, and whether your plate is worth the investment.

With WearCalc 2.1, calculating component wear and optimizing your choice of wear plate just got easier.

This powerful prediction software — offered free of charge to SSAB’s wear plate customers — lets you quickly and easily calculate the relative service life for all Hardox® wear parts of different grades, so you can choose the best plate for your needs. WearCalc 2.1 predicts erosion and impact wear as well as sliding wear.

The impact wear model analyzes severe damage involving crater formation and extruded lips during impact, and model damage resulting in plastic deformation of the surface. The erosion model predicts whether makeup of the abrasive materials will cause edges to penetrate the steel surface or to break. At the micro level, this model uses mineral hardness to calculate erosion on different types of wear plate.

The sliding wear model is based on two limiting curves representing the types of surface damage, plastic or cutting. The relationship between the hardness of the steel and the hardness of the abrasive material determines the damage mechanism and thus the relative service life.

WeldCalc™ 2.2 gives you optimized welding recommendations at your fingertips.

Weldcalc 2.2 - Welding calculator

WeldCalc 2.2 from SSAB makes decades of welding experience available in an interactive, web-based application to help fabricators optimize the welding process. It calculates and presents welding recommendations for both Hardox® and Strenx® steels.

How WeldCalc works

Users input the desired mechanical properties, welding process and plate materials. Based on this information, a “tolerance box” is calculated, showing the allowed span of heat input and preheat/interpass temperature. In addition the maximum hardness levels in the heat affected zone (HAZ) can be calculated.

The web-based interface has functions for saving, opening and editing your welding cases, making it easy to view and apply the results. Recommendations for welding include MAG welding, MMA welding, SAW, TIG welding, laser welding, laser-hybrid welding and plasma welding.

Features and benefits

  • Features an intuitive user interface and many new functions, making the results even easier to calculate and apply.
  • Users can choose the properties most important in a given welded construction, such as whether to prioritize optimum toughness in the joint or optimum production efficiency.
  • Users can save or export the results.
  • Logs can be opened, edited and saved again.
  • Web-based and always up-to-date.
