LAMPIRAN 1
STAINLESS STEEL GRADES
• 200 Series – austenitic chromium-nickel-manganese alloys
o Type 201 – austenitic that is hardenable through cold working
o Type 202 – austenitic general purpose stainless steel
• 300 Series – austenitic chromium-nickel alloys
o Type 301 – highly ductile, for formed products. Also hardens rapidly during mechanical working. Good weldability. Better wear resistance and fatigue strength than 304.
o Type 302 – same corrosion resistance as 304, with slightly higher strength due to additional carbon.
o Type 303 – easier machining version of 304 via addition of sulfur and phosphorus. Also referred to as "A1" in accordance with ISO 3506.
o Type 304 – the most common grade; the classic 18/8 stainless steel. Also referred to as "A2" in accordance with ISO 3506.
o Type 304L – the 304 grade but specially modified for welding.
o Type 309 – better temperature resistance than 304
o Type 316 – the second most common grade (after 304); for food and surgical stainless steel uses; alloy addition of molybdenum prevents specific forms of corrosion. 316 steel is used in the manufacture and handling of food and pharmaceutical products where it is often required in order to minimize metallic contamination. It is also known as marine grade stainless steel due to its increased resistance to chloride corrosion compared to type 304. SS316 is often used for building nuclear reprocessing plants. Most watches that are made of stainless steel are made of Type 316L; Rolex is an exception in that they use Type 904L. Also referred to as "A4" in accordance with ISO 3506. 316Ti (which includes titanium for heat resistance) is used in flexible chimney liners, and is able to withstand temperatures up to 2000 degrees Fahrenheit, the hottest possible temperature of a chimney fire.
o Type 321 – similar to 304 but lower risk of weld decay due to addition of titanium. See also 347 with addition of niobium for desensitization during welding.
• 400 Series – ferritic and martensitic chromium alloys
o Type 405 – a ferritic especially made for welding applications
o Type 408 – heat-resistant; poor corrosion resistance; 11% chromium, 8% nickel.
o Type 409 – cheapest type; used for automobile exhausts; ferritic (iron/chromium only).
o Type 410 – martensitic (high-strength iron/chromium). Wear-resistant, but less corrosion-resistant.
o Type 416 – easy to machine due to additional sulfur
o Type 420 – Cutlery Grade martensitic; similar to the Brearley's original rustless steel. Excellent polishability.
o Type 430 – decorative, e.g., for automotive trim; ferritic. Good formability, but with reduced temperature and corrosion resistance.
o Type 440 – a higher grade of cutlery steel, with more carbon in it, which allows for much better edge retention when the steel is heat-treated properly. It can be hardened to around Rockwell 58 hardness, making it one of the hardest stainless steels. Due to its toughness and relatively low cost, most display-only and replica swords or knives are made of 440 stainless. Also known as razor blade steel. Available in four grades: 440A, 440B, 440C, and the uncommon 440F (free machinable). 440A, having the least amount of carbon in it, is the most stain-resistant; 440C, having the most, is the strongest and is usually considered a more desirable choice in knifemaking than 440A except for diving or other salt-water applications.
o Type 446 – For elevated temperature service
• 500 Series – heat-resisting chromium alloys
• 600 Series – martensitic precipitation hardening alloys (Sumber: en.wikipedia.org)

Uji Korosi Stainless Steel 304 Dalam Larutan Asam (H2SO4)
Uji korosi untuk stainless steel 304 seperti yang telah dilakukan oleh saudara Yuris Werenfridus Baur dan Rois Setiyo Utomo, yaitu menguji laju korosi pada stainless steel 304 dalam larutan asam (H2SO4), dengan derajat keasaman (pH) 1, pada suhu 70oC selama 6 jam dan dilanjutkan pada suhu 29oC selama 18 jam secara periodik, dengan perlakuan tanpa pengelasan serta setelah mengalami pengelasan TIG, di Laboratorium Farmasi Universitas Sanata Dharma Yogyakarta.
Pengujian stainless steel 304 tanpa pengelasan dilakukan pada dua bahan yang sama ketebalannya yaitu 3 mm, tetapi berbeda beratnya. Berat benda uji 1 adalah 8,576 gram dan berat benda uji 2 adalah 14,543 gam. Dari hasil uji korosi tersebut, didapat hasil seperti pada tabel berikut:

Analisis Laju Korosi Stainless Steel 304 Dalam Larutan H2SO4
Perhitungan atau analisis laju korosi dapat dihitung dengan menggunakan rumus :
Laju korosi = ∆
dengan :
Δy = besarnya perubahan (m ,mm, kg, gram) T = Waktu (Jam, Bulan, Tahun)
1. Tanpa Pengelasan
Pada pengujian stainless steel 304 tanpa pengelasan, karena tidak terjadi perubahan berat dari kedua spesimen sampai dengan minggu ke-12 maka laju korosi yang terjadi adalah 0 (gram/hari).
Sumber: Werenfridus Baur. Yuris, Laju Korosi Stainless Steel 304 Dalam Larutan H2SO4 pH 1, 2007
Data yang diperoleh dari hasil penelitian ini menunjukkan bahwa berat spesimen sampai minggu ke-12 tidak mengalami perubahan berat dan otomatis dari segi ukuran juga tidak mengalami perubahan. Akan tetapi terjadi perubahan warna yang disebabkan karena kotoran yang menempel pada permukaan spesimen setelah bereaksi dengan larutan H2SO4.
2. Dengan Pengelasan
Data yang diperoleh dari hasil pengujian stainless steel 304 dengan pengelasan, menunjukkan bahwa berat spesimen sampai minggu ke-12 mengalami perubahan berat sehingga spesimen juga mengalami perubahan ukuran. Sehingga diperoleh laju korosi seperti pada tabel berikut.

CORROSION RATE CONVERSION
The following charts provide a simple way to convert data between the most common corrosion units in usage, i.e. corrosion current (mA cm-2) , mass loss (g m-2 day-1) and penetration rates (mm y-1 or mpy) for all metals or for steel
mA cm-2 mm year-1 mpy g m-2 day-1 mA cm-2 1 3.28 M/nd 129 M/nd 8.95 M/n
mm year-1 0.306 nd/M 1 39.4 2.74 d
mpy 0.00777 nd/M 0.0254 1 0.0694 d
g m-2 day-1 0.112 n/M 0.365 /d 14.4 /d 1 where:
mpy = milli-inch per year
n = number of electrons freed by the corrosion reaction M = atomic mass
d = density
Note: you should read the Table from left to right, i.e.:
1 mA cm-2 = (3.28 M/nd) mm y-1 = (129 M/nd) mpy = (8.95 M/n) g m-2 day-1 For example, if the metal is steel or iron (Fe), n =2, M = 55.85 g and d = 7.88 g cm-3 and the Table of conversion becomes:
mA cm-2 mm year-1 mpy g m-2 day-1
mA cm-2 1 11.6 456 249
mm year-1 0.0863 1 39.4 21.6
mpy 0.00219 0.0254 1 0.547
g m-2 day-1 0.00401 0.0463 1.83 1
Note: you should read the Table from left to right, i.e.:
1 mA cm-2 = 11.6 mm y-1 = 456 mpy = 249 g m-2 day-1 (Sumber: www.corrosion-doctors.org)
