In line with the steel protectionism seen in many countries, as covered in the global steel industry outlook, Indonesia continues to adjust its steel import tariffs to protect domestic producers from cheap imported steel, while trying to stay balanced with the needs of downstream industries that rely on steel as a raw material. Background: Why

Indonesia’s mineral downstreaming policy, which bans raw ore exports and requires domestic processing, has fundamentally changed the country’s mining landscape over the past decade. Nickel is the most prominent example of this policy, and its momentum continues into 2026 with increasingly complex dynamics. Growth in Nickel Smelter Capacity Since the ban on raw nickel ore

How do you make sure a cast part is free of internal defects such as porosity or cracks without cutting or damaging it? That is exactly the question Non-Destructive Testing (NDT) answers. NDT is a group of inspection methods that detect material defects without changing or damaging the function and shape of the part being

Corrosion is more than the rust that shows up on old iron. In industry, it is one of the most expensive and most underestimated causes of material failure, from leaking pipes in oil refineries and cracks in bridge structures to ship components failing out at sea. Understanding the types of corrosion and how they work

Two parts made from metal with identical chemical composition can have very different hardness, ductility, and wear resistance, purely because of the heat treatment each one received. That is what makes heat treatment one of the most fundamental processes in physical metallurgy, and a topic anyone who works with metals needs to understand, whether in

The global steel industry is at a fairly dramatic crossroads. On one hand, demand from construction and manufacturing keeps growing in many regions. On the other, the industry faces three pressures at once: chronic overcapacity, escalating trade tariffs between countries, and increasingly urgent demands for decarbonization. The Overcapacity Problem That Will Not Go Away Global
