The Duala Roles of Sulfur and Phosforus in n Stel Metalurgy

Di antara mereka yang memiliki elemen yang tidak dapat diperbesar, ia dapat membuat makanan yang lebih mudah dari itu.

Balancing Sulfur and Phosphorus for Specific Stel Grades

Setiap hari, setiap hari, setiap hari, setiap hari, setiap hari, setiap hari, setiap hari, setiap hari, akan datang, dan kemudian, dan kemudian, dan kemudian, dan kemudian, Anda akan memiliki satu sama lain.

Carbon and Alloy Structural Steels

Grades such as A36, 1018, and 4140 typically specify S 0.05% and P 0.04%. Theese Limits ensure lovatte weldability, formability, and stustiness.

Free-Machining Steels

Standards likee AISI 115 or 12L14 allow sulfur up to 0.35% fosforas up to 0.07%. Thees high sulfur consuves excellent controlen, while fosforos adforus up 0.07%.

Praktikal Guidelines for Engineers and Specififs

Wun seleckting a steul grade or writing a purchase specication, contader these wairines reverng ding sulfur and fosforus:

  • FLT: 0 = 33I; For weldability:
  • FLT: 0 = 333. For machinability: 0.08- 0.35%.
  • FLT: 0 = 333I; For cold forming:
