Steel manufacture is a slow process of development lasting over many years and employing the skills of many men.
Steel manufacture is a slow process of development lasting over many years and employing the skills of many men. Steel is never 'invented' in the usually understood sense of the word - but over a long period of time certain qualities are 'bred' into a steel-type which fit it for certain purposes.
In one of the largest stainless steel producing plant in the British Commonwealth - producing 1/3 of Britain's alloy steel and 1/4 of this country's stainless steel requirements - Messrs. Samuel Fox of Stocksbridge near Sheffield have developed a steel they call Jethete M 151 which puts this country in the forefront of high-tennis stainless steels for use in the aircraft, the high speed motor, the turbine, and the atomic power industry.
Visnews had the exclusive facility on Thursday last of filming inside the Stocksbridge works, and watched Jethete M 151 and other stainless steels being manufactured.
The electric furnace in which the highly secret component of Jethete M 151 are smelted is the largest in the British Commonwealth - it smelts 70 tons of steel at a time and when operating its 3 electrodes take as much current as would supply a population of 150,000. From the furnace the melt is cast in ingots each 9 feet high and two feet square - these ingots are then rolled at red heat in the cogging mill to make the final strip steel used - among other things - for the cowls for jet engines.
Jethete M 151 is an outstanding example of British achievement; in it the qualities of high tensile, heat resisting steel are all combined. If you ask them at Stocksbridge - in what way it is better than other steels? - they can point to a collection of qualities all of which add up to a world-beater. Steel researchers now anticipate the needs of the industry. What is industry going to need in ten years, they are saying. And that is what they are producing. Jethete M 151 has already allowed designers in the rocket and atomic industries to their designs. With greater strength per pound at their fingertips they can now push ahead to lead the world.
