EZ Drill Stainless Steel Plate

Semeier improves its mechanical machinability with molten steel and calcium treatment, which controls the size, composition and distribution of oxides。These oxides play an important role as lubricants to maximize feed rates。

E-z drill steel has the same yield, ductility, tensile strength, hardness, strength and corrosion resistance as standard austenitic steel。

Heat exchanger tubes are processed using semeier's E-Z drill plate

厚度 & 牌号
E-z drill steel plate common thickness 3/8" (9.5 mm) to 6" (152.4 mm), the main brands are 304,304H,304L,316 and 316L。

Material certification
The E-Z drill material has been certified by ASTM,ASME and QQS-766。

Performance improvement
If drilled, reamed, and slotted with carbide bits, e-Z drill plates can increase feed rates by 30% without reducing bore wear。
