Steel Open hearth steelmaking Britannica

Steel Steel Open hearth steelmakingThough it has been almost completely replaced by BOF and EAF steelmaking in many highly industrialized countries, the open hearth nevertheless accounts for about one sixth of all steel produced worldwide. The open hearth furnace (OHF) uses the heat of combustion of gaseous or liquid fuels to convert a charge of scrap and liquid blast furnace iron to Open hearth process metallurgy BritannicaOpen hearth process, also called Siemens martin Process, steelmaking technique that for most of the 20th century accounted for the major part of all steel made in the world. William Siemens, a German living in England in the 1860s, seeking a means of increasing the temperature in a metallurgical furnace, resurrected an old proposal for using the waste heat given off by the furnace; directing ASTM A663 / A663M 17 Standard Specification for Steel The steel shall be made by the open hearth, basic oxygen, or electric furnace process. The specimens shall undergo a tension test to determine tensile strength, yield point and elongation. The merchant quality bars shall be from visible pipe; however, they may contain pronounced chemical segregation.

API 5L X70 Pipe Specifications Octalsteel

API 5L X70 steel pipe has a minimum yield strength of 70,300 psi or 485 Mpa. The current X70 steel pipe are all controlled micro alloyed carbon manganese steels. The micro alloys elements are mainly Nb, V and Ti, and the total content of micro alloys does not exceed 0.15%.SAE steel grades Quality Tools & Services, Inc.The prefix "C" denoted open hearth furnace, electric arc furnace or basic oxygen furnace, while "E" denotes electric arc furnace steel. Prior to 1995 the AISI was also involved, and the standard was designated the AISI/SAE steel grades. The AISI stopped being involved because it never wrote any of the specifications.Steel Making Processes Steel term Steel grades The nitrogen content of steels made by the Bessemer and electric arc processes is about 0,01 0,25% compared with about 0,002 0,008% in open hearth steels. Oxygen processes The high nitrogen content of Bessemer steel is a disadvantage for certain cold forming applications and continental works have, in recent years, developed modified processes

Steel Bessemer steel Britannica

Steel Steel Bessemer steelBulk steel production was made possible by Henry Bessemer in 1855, when he obtained British patents for a pneumatic steelmaking process. (A similar process is said to have been used in the United States by William Kelly in 1851, but it was not patented until 1857.) Bessemer used a pear shaped vessel lined with ganister, a refractory material containing silica 1926 O.H. Structural Steel?
