1.4028 (3H13, X30CR13) - is a martensitic, chromium grade of a group of stainless steels designed for hardening and tempering. The steel is included in the list of related counterparts - 0H13, 1H13, 2H13 and 4H13 - a group of materials without Nickel, containing an average of 13% Chromium, which are distinguished mainly by their carbon content in the chemical composition, and thus higher strength properties. The differences have a significant impact on the possibility of obtaining particular hardness ranges and levels of corrosion resistance, where 3H13 / X30Cr13 is a balanced choice between 2H13 and 4H13.

Regular maintenance of 1.4028 stainless steel (3H13, X30CR13) prevents deposits and maintains its luster. It also makes it easier to remove spots and tarnish. Cleaning should be done before there is a visible layer of dirt or fingerprints, so the danger of permanent discoloration of the steel surface is minimized. For cleaning, do not use agents that contain: chlorine, salt, acids and bleach.

• Shackler (sailor's wrench) for unscrewing / tightening shackles
