316 Kumparan Baja Tahan Karat
316 stainless steel coil is a high-performance austenitic stainless steel with enhanced corrosion resistance due to molybdenum content. With stable mechanical properties, strong chloride resistance, and a wide range of available sizes and finishes, it is ideal for marine, kimia, makanan, dan aplikasi industri.
- Keterangan
316 kumparan baja tahan karat is an austenitic chromium-nickel-molybdenum stainless steel known for its excellent corrosion resistance, especially in chloride and marine environments. Dibandingkan dengan 304 baja tahan karat, 316 mengandung molibdenum (Mo), which significantly improves resistance to pitting and crevice corrosion.
It is widely used in marine equipment, Pemrosesan Kimia, food production, alat kesehatan, dan aplikasi arsitektur.
1. Komposisi Kimia dari 316 Baja Tahan Karat (Khas %)
| Elemen | Isi (%) | Fungsi |
|---|---|---|
| Karbon (C) | ≤0,08 | Controls strength and hardness |
| Kromium (Kr) | 16.0–18.0 | Memberikan ketahanan terhadap korosi |
| Nikel (Di dalam) | 10.0–14.0 | Menstabilkan struktur austenitik |
| molibdenum (Mo) | 2.0–3.0 | Improves pitting and chloride resistance |
| mangan (M N) | ≤2.00 | Improves hot working properties |
| Silikon (Dan) | ≤1.00 | Strengthens steel matrix |
| Fosfor (P) | ≤0.045 | Controlled impurity element |
| Sulfur (S) | ≤0.030 | Meningkatkan kemampuan mesin (limited) |
For improved weldability and reduced intergranular corrosion risk, 316L grade is available with lower carbon content (≤0,03%).
2. Sifat Mekanik (Kondisi Anil)
| Milik | Nilai Khas |
|---|---|
| Kekuatan Hasil | ≥205 MPa |
| Kekuatan Tarik | ≥515 MPa |
| Pemanjangan | ≥40% |
| Kekerasan | ≤95HRB |
316 stainless steel coil offers excellent ductility, sifat mampu bentuk, and weldability in the annealed condition.
