Since ULMA\u2019s birth,\u00a0forged steel<\/strong>\u00a0has been our reason for being. Everything we have achieved over the past few decades has been thanks to the passion, effort and dedication we have put into this material that is so precious to us. The majority of our products have forged steel as their raw material\u2014a material that we modify in form and internal structure through forging techniques that we carry out, always above recrystallization temperatures.<\/p>\r\n\r\n\r\n\r\n

This is our forging process.<\/strong><\/h2>\r\n\r\n\r\n\r\n

The forging process<\/a> happens on our presses. Using strong blows and high pressure, the presses form predetermined volumes and shapes using tools such as molds and dies. The pieces coming from the forges are then machined to give them their finish with minimum possible intervention to optimize their end characteristics.<\/p>\r\n\r\n\r\n\r\n

In most cases,\u00a0forging must be done at a temperature between 800 and 1000\u00baC,\u00a0<\/strong>though it can also be carried out at\u00a0room temperature\u00a0<\/strong>in a process known as \u201ccold forming.\u201d To eliminate the internal stresses that arise during forging, we also perform a heat treatment called \u201cnormalization.\u201d<\/p>\r\n\r\n\r\n\r\n

What is forged steel?<\/strong><\/h2>\r\n\r\n\r\n\r\n

Forged steel is a material resulting from\u00a0alloying iron and carbon\u00a0<\/strong>under extremely high pressure. Forged steel has less surface porosity, a finer grain structure, more tensile and fatigue strength, and greater ductility than any other processed steel.<\/p>\r\n\r\n\r\n\r\n

When the steel is heated to forging temperature, it becomes\u00a0ductile and malleable<\/strong>, allowing it to be molded into the required shape through the application of force and pressure. Through our processing methods and steel forging, we can shape a permanent steel part without it cracking.<\/p>\r\n\r\n\r\n\r\n

What are the types of forged steel?<\/strong><\/h2>\r\n\r\n\r\n\r\n

We classify steel forging into three different categories, depending on the forming temperature.<\/p>\r\n\r\n\r\n\r\n

Hot forged steel<\/em><\/h3>\r\n\r\n\r\n\r\n

The forging temperature is between\u00a0950 and 1250\u00baC,<\/strong>\u00a0which is above the temperature of recrystallization. Hot forged steel results in good formability and requires low force to shape.<\/p>\r\n\r\n\r\n\r\n

Hardened steel forging<\/em><\/h3>\r\n\r\n\r\n\r\n

The forging temperature is between\u00a0750 and 950\u00baC<\/strong>. This temperature leads to limited ductility and requires higher forming forces than hot forging. One of its great advantages is that it is halfway between hot and cold forging, which makes it more versatile.<\/p>\r\n\r\n\r\n\r\n

Cold forged steel<\/em><\/h3>\r\n\r\n\r\n\r\n

The forging temperature is done under \u201droom conditions,\u201d under temperatures of\u00a0up to 150\u00baC<\/strong>. This type of forging, which results in low formability, requires high forming forces. It has the great advantage of allowing better conservation of the material and a better surface finish.<\/p>\r\n\r\n
