Material Notes:
AK Steel 304L is an extra low-carbon variation of Type 304, that eliminates carbide precipitation due to welding. AK Steel 304L can be used in the “as-welded” condition, even in severe corrosive conditions. It often eliminates the necessity of annealing weldments except for applications specifying stress relief. It has slightly lower mechanical properties than Type 304.

Material Notes:
Description: Isotope B10 has the property to capture neutrons produced by nuclear reactions. Natural boron contains about 19.9 at% or 18.45 wt % of B10 isotope, the remaining being B11 isotope. NUCL 18.10 B4 grade is a 304 stainless steel obtained by ingot casting and alloyed with 1 to 1,24 wt% natural boron additions. In order to avoid ferrite grain which reduce the ductility of the alloy, NUCL 18.10 B4 grade has been overalloyed in Nickel when compared to 304 grades. Molybdenum additions are sometimes considered to increase the corrosion resistance properties. The ingots rolled into plates are considered for nuclear applications (transport, casks, storage -in pools) of nuclear (waste) products. For specific purposes, some other grades are sometimes used. The boron content may thus be included in the 0.2-2 weight % range or/and alloys obtained by powder metallurgy (A type). CLI-FAFER can also produce 18-10 A or B type boron alloyed grades (included B10 enriched grades). Among the family of boron enriched 304 grades, NUCL 18-10 B4 grade is the most commonly used.

Material Notes:
Austenitic Cr-Ni stainless steel. Better corrosion resistance than Type 302. High ductility, excellent drawing, forming, and spinning properties. Essentially non-magnetic, becomes slightly magnetic when cold worked. Low carbon content means less carbide precipitation in the heat-affected zone during welding and a lower susceptibility to intergranular corrosion.

Applications: beer kegs, bellows, chemical equipment, coal hopper linings, cooking equipment, cooling coils, cryogenic vessels, dairy equipment, evaporators, flatware utensils, feedwater tubing, flexible metal hose, food processing equipment, hospital surgical equipment, hypodermic needles, kitchen sinks, marine equipment and fasteners, nuclear vessels, oil well filter screens, refrigeration equipment, paper industry, pots and pans, pressure vessels, sanitary fittings, valves, shipping drums, spinning, still tubes, textile dyeing equipment, tubing.

Corrosion Resistance: resists most oxidizing acids and salt spray.
