Adopt Standard: API Specification 2H
API steel grade:
API 2H Grade 42 |
API 2H Grade 50 |
API 2H Grade 50 is a carbon manganese steel plate for offshore platform tubular joints and welded construction of offshore structures. API means the American petroleum institute.
All of steel grade in API 2H Grade 50 need be normalized. The max CEQ should be 0.43-0.45% in usual. Grade 50 shall be marked API 2H-50 or API 2H-50N
Henan Bebon exported API 2H GRADE 50 steel material directly from our mill in the competitive price from sales department. Each plate has the Mill Certificate Test EN10204 3.2 Version.
Henan Bebon International Co., Ltd sincerely hope old and new customers to visit our mill for a long steel business
