Characteristic
Stainless steel grade 316 termasuk kategori austenitic grade. Stainless 316 adalah chromium-nickel stainless steel yang mengandung molybdenum 2-3 persen, sedangkan stainless 201 & 304 tidak ada penambahan unsur molibdenum. Kandungan Molybdenum meningkatkan ketahanan terhadap korosi sehingga ideal untuk lingkungan yang lebih asam serta tahan terhadap suhu tinggi.
Stainless steel grade 316L adalah versi rendah karbon dari tipe 316. Karbon rendah yang terkandung didalam tipe 316L meminimalkan pengendapan karbit yang merusak sebagai hasil dari proses pengelasan. Sehingga tipe 316L digunakan ketika dibutuhkan pengelasan yang memerlukan ketahanan korosi maksimal
Stainless steel Grade 201 memiliki kemampuan formabilitas yang baik, tahan korosi, dan kemampuan fabrikasi. Grade 201 memiliki kemiripan dengan stainless steel 301.
Availability
Stainless steel 316 & 201 available in Sheet, Bar, Wire, Rod, Strip, tube, pipe, and Channel.
