A4 Stainless Steel Bolts is often also referred to as ‘A4 Marine Grade Stainless Steel Bolts’ and has the very highest level of corrosion resistance. Because of corrosion resistance this grade is used for surgical implants and used for underwater installations. A4-25H : This represents a “316” type tapping screw to part 4 with a minimum Vickers hardness of 250 HV Low carbon variants of the austenitic grades, if used may be additionally marked in the form

A4L-70 or A4L-25H : These annexes specifically note that the risk of failure to bolts, screws and studs by chloride induced stress corrosion cracking (eg in indoor swimming pools) can be reduced by using grade types, 1.4439, 1.4439, 1.4529, 1.4462. These grades are not however covered in the standard grade schedules.

A4-70 vs a4-80 bolt

A4-70 and a4-80 bolt both are non-magnetic and Austenitic grade of stainless steel grade fasteners. A4 70 Bolt comes in the grade A4, as does the A4 80 Bolt and so these bolts and also the A4-50 Bolt are covered in 3 property classes and these are 80 (high-strength), 70 (cold-worked) and 50 (soft). The most commonly used of all of these, being those of the 70 class. As molybdenum has been added in the making of these kinds of bolts, their resistance to corrosion is heightened and they are in big demand for use in the marine sector, in the medical field and also in the chemical processing industry.
