SSAB and Ruukki have merged to form a stronger combined company called New SSAB. The merger strengthens New SSAB's customer offering and enhances its ability to invest in product development. It is expected to realize annual cost synergies of up to SEK 1.4 billion over three years. New SSAB will be a leading steel and construction solutions company with operations in the Nordic region, US, and other global markets. It has five divisions and aims to grow especially in advanced high strength steels.
For construction professionals and sales personnel.

Annealing is a heat treatment process used to alter the microstructure of metals to achieve desired properties. It involves heating metals to specific temperatures, holding for a period of time, then slowly cooling. The key stages of annealing are recovery, recrystallization, and grain growth. Recovery relieves internal stresses through dislocation movement. Recrystallization involves nucleation of new strain-free grains. Grain growth increases grain size. Together, these stages reduce hardness and brittleness while increasing ductility. Different annealing types like full annealing, stress relief annealing, and spheroidizing annealing are used to achieve different microstructures and properties for various applications.
The document discusses various heat treatment processes. It defines heat treatment as operations involving heating and cooling of metals/alloys in their solid state to obtain desirable properties. It describes the stages of heat treatment as heating, soaking, and cooling. It then discusses various heat treatment processes like annealing, normalizing, hardening, and tempering in detail including their purposes, methods, and effects on material properties.
This document provides information on various heat treatment processes for steel, including annealing, normalizing, hardening, and tempering. It describes the purposes and procedures for each process. Key points include:
- Annealing involves heating steel above the upper critical temperature, then slow cooling to relieve stresses and improve ductility.
- Normalizing also involves heating above the upper critical temperature, but the steel is air cooled to refine grain size while retaining some strength.
- Hardening greatly increases strength by heating steel to the austenitizing temperature then quenching in water or oil to form martensite.
- Tempering is then used to reduce brittleness by reheating hardened steel to lower temperatures.
This document discusses heat treatment methods for controlling material properties of metals and alloys. It describes how heating metals to certain temperatures can cause phase changes that modify microstructures and influence properties like strength, hardness, and wear resistance. Specific heat treatment methods are outlined, including hardening, annealing, normalizing, and tempering, and how they impact phase transformations and material properties on iron-carbon phase diagrams. Surface hardening techniques are also mentioned.
This document provides information about various heat treatment processes including annealing, normalizing, hardening, tempering, and hardenability. It describes the purposes and procedures for each process, including the effects on microstructure and material properties. Examples are given to illustrate how to determine the final microstructure based on time-temperature treatments using TTT diagrams.

De eerste slide geeft de wereld van de patiënt neer met een ervaring vanuit mijn blog. Wat betekent borstkanker in feiten en cijfers. Wat is de aanpak van de Borstkankervereniging Nederland? Een nieuw project is gestart EBI (ervaringen bundelen en inzetten). En hoe vertaalt zich dit in actuele voorbeelden. Waar het om gaat? Cut the crap and find a cure! Of het nu gaat om de patiëntenvereniging, leverancier, zorgverlener/-instelling of patiënt...samen moeten we zoeken naar nieuwe geïntegreerde paden!
