The bessemer process and the open-heart process
The Open Hearth Furnace and the Bessemer Process <- thanks veeeeeeerrrrrrrrrrryyyyyyyyyyyyyy mmmmmmuuuuuuuuuuuucccccccccccccccchhhhhhhhhhhhhhhhhhh!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
The Bessemer process was the first inexpensive industrial process for the mass production of steel from molten pig iron before the development of the open hearth furnace.
The Bessemer process was the first inexpensive industrial process for the mass-production of steel from molten pig iron. The process is named after its inventor, Henry Bessemer, who took out a patent on the process in 1855. The process was independently discovered in 1851 by William Kelly.
In 1865, the French engineer Pierre-Émile Martin took out a license from Siemens and first applied his furnace for making steel. Their process was known as the Siemens-Martin process, and the furnace as an "open-hearth" furnace.
The steel industry benefited from the development of the Bessemer process. It was the steel industryâ??s first low cost process for mass production prior to the open hearth furnace. Named after inventor, Henry Bessemer who patented the industrial process. it had been used outside Europe for hundreds of years, just not on an industrial basis.

Open My Heart was created in 1998.
Answer The Society of Automotive Engineers (SAE) set up a system of classifying steels and alloys which uses a 4 digit code with letter prefixes. The letters before the 4 digit code identify what method the steel was made with. An "A" before the 4 digits means it's an alloy steel made over an open hearth. A "B" means the steel is carbon steel which is made with an acid bessemer process. A "C" prefix means the steel is a carbon steel made using a basic open hearth. A "D" means the steel is carbon steel made using an acid open hearth. When an "E" is present in the prefix, it means the steel is made using an electric furnace.
