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.

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:
