特殊合金脫臘鑄件

根據不同的圖面及需求,本公司能提供給您在脫臘鑄件方面所需要的特殊材質,以配合客戶在不同流體與環 境下的需求。

測試

客戶對於特殊材質的產品,通常會要求進行某些方面的測試。在這 方面會偕同第三方(Third parties)的幫忙,針對特殊產品進行必要的認證測試,以此確保特殊合金在各方面都能符合標準。底下是這些測試可能包含的項目:

1) Corrossion Testing(腐蝕測試):(ASTM G48)在4*4cm到10*10cm的測試範圍內測試72小時(或24小時,依照需求)。

2) Micrographic Examination(顯微照相測試):在每個測試範圍內提供100倍到50倍照片。

3) PMI (材質測定), 陸功工業以最先進之光譜分析設備,分析每一爐鑄件之正確成份,以確保每一精密鑄件皆能符合客戶之需求。

Material Properties

哈氏合金球閥(Hastelloy C)

The wonderful corrion resistance alloy. Hastelloy C 276 has excellent ability to resist strong oxidizers such as ferric and cupric chlorides, chlorine. Casting grade: CW12MW

HC-22 合金球閥(Hastelloy C-22)

Hastelloy C-22 is very similar to Hastelloy C-276, some called New Hastelloy C. The casting grade of Hastelloy C-22 is CX2MW. This material was popular in pharmaceutical industries and in chemical processing, pollution control, waste water, etc. Hastelloy C-22 is better than C-276 when used in saturated wet Chlorine condition.

鈦合金球閥(Titanium)

Titanium (ASTM Grade 2) is light, and with excellent corrosion resistance in highly oxidizing to mildly reducing environment, including Chlorides. Ti has good impact properties at low temperature, it can be used at both cold and hot works.

Alloy 59 valves

Alloy 59 is one type of Nickel-Chromium-Molybdenum alloy.￿ It is noted for the resistance of wide range of corrosive media and environments, both for osidizing and reducing. Casting grade: CX2M

Alloy 625 valves

Alloy 625 is one of Nickel-Chromium-Molybdenum alloy.￿ It is with high strength and excellent wide range of corrosive resistance, especially to pitting and crevice corrosion. Casting grade: CW6MC

蒙氏合金球閥(Monel)

The nickel content alloy with high strength with excellent corrosion resistance for media including sea water, sulfuric acid, alkali media. Casting grade: M35-1

Alloy 20 valves

Alloy 20 used in aerospace cryogenic fuel tanks with low density and exhibits high strength, high elasticity, and high fatigue durability. Casting grade: CN7M

254 SMO valves

254 SMO (1.4547/ UNS S31254/ A182 F44), Casting Grade CK3MCuN is deslgned to resistance to pitting and crevice corrosion.￿ And offers Chloride resistance superior to that of Alloy 904L, Alloy 20, Alloy 825
