Single and double-stranded, Lang's lay and regular lay, Seale and Warrington, running and standing ropes, and the 1834 patent that revolutionised mine hoisting. - [Assemblable wire rope end, the quick solution](https://menet-trend.hu/en/nonox-world/assemblable-wire-rope-end-the-quick-solution.md) — Swaged wire rope ends need a press machine, and once swaged the joint can no longer be undone. Assemblable wire rope ends eliminate both drawbacks: a releasable joint with no looping, assembled with two open-ended spanners. Their components and the assembly procedure. - [Blood on the balcony](https://menet-trend.hu/en/nonox-world/blood-on-the-balcony.md) — In the mild early-summer night, creaking and banging breaks the silence of the tenement house into blade-sharp splinters. A dark figure, a weapon-like object, a few drops of blood on the walkway. This story is so real that it could even be true. - [Installing solar collectors and solar panels by replacing the factory mounting frame](https://menet-trend.hu/en/nonox-world/installing-solar-collectors-and-solar-panels-by-replacing-the-factory-mounting-frame.md) — The price of factory mounting frames is rather steep. Replacing them requires some thought, but it is by no means an insoluble task: the fixing must withstand +100ºC and -20ºC, frost, damp and wind, and must stay releasable after 10-20 years. - [Pipe fittings, fittings](https://menet-trend.hu/en/nonox-world/pipe-fittings-fittings.md) — How does water flow from the tap? A pipeline network criss-crosses our walls and the depths of the earth, and its elements are the pipe fittings. Elbows, T pieces, unions, flanges, quick couplings and ball valves, in cast iron, A2 stainless or A4 acid-resistant steel. - [The corrosion resistance of the A2 stainless and A4 acid-resistant screw raw materials](https://menet-trend.hu/en/nonox-world/the-corrosion-resistance-of-the-a2-stainless-and-a4-acid-resistant-screw-raw-materials.md) — Austenitic stainless and acid-resistant steels belong in the category of active corrosion protection thanks to their alloying materials. Even so, they can corrode in practice. Rust contamination, surface, local, contact, stress and mechanical corrosion, and how to guard against each. - [Corrosion-resistant alloys](https://menet-trend.hu/en/nonox-world/corrosion-resistant-alloys.md) — Protective coatings only protect while they remain intact. The other fundamental method of protection against corrosion is alloying, thanks to which stainless and acid-resistant steels came into being. From iron-carbon alloys to the welding and standardisation of A2 and A4 grades. - [How to protect against rust](https://menet-trend.hu/en/nonox-world/how-to-protect-against-rust.md) — By definition, corrosion is the destruction of metals by an electrochemical process. In a dry medium iron does not rust, yet corrosion causes an estimated HUF 50 billion of damage a year in Hungary. Local cells, protective coatings, galvanising and cathodic protection explained. - [Galling of stainless screws](https://menet-trend.hu/en/nonox-world/galling-of-stainless-screws.md) — NOT a material defect! NOT caused by corrosion! NOT a common phenomenon, but it can happen. With austenitic screws the thread can seize as if welded, already during the first tightening. What causes galling, and which methods reliably prevent it? - [Steels and their properties](https://menet-trend.hu/en/nonox-world/steels-and-their-properties.md) — Iron is an important element of living organisms and one of our most heavily used industrial materials, especially its alloy with carbon: steel. From classification and the effect of carbon to the alloying elements behind corrosion-resistant and acid-resistant grades, here is what shapes the properties of steels. - [Steels and their properties II](https://menet-trend.hu/en/nonox-world/steels-and-their-properties-ii.md) — Structural steels. Materials such as steel are things we encounter primarily in practice, as users, so it is worth discussing some of their properties on the basis of their fields of application. Non-alloy structural steels are usually supplied in the hot-rolled or forged condition. - [Heat treatment](https://menet-trend.hu/en/nonox-world/heat-treatment.md) — Heat treatment is a technological operation consisting of controlled heating and heat transfer and/or cooling, by which the properties of products can be modified to suit their application. There are certain heat treatments that are used for a particular alloy family – for example for stainless and acid-resistant steels. - [How to avoid galling of stainless steel fasteners](https://menet-trend.hu/en/nonox-world/how-to-avoid-galling-of-stainless-steel-fasteners.md) — With NONOX stainless steel screw joints, galling of rough surfaces can still cause problems even today. It is not uncommon for the phenomenon to be assumed to be caused by corrosion; in contrast, other triggering causes usually lie in the background, such as coarse thread machining or other surface damage. - [Designations of stainless steels](https://menet-trend.hu/en/nonox-world/designations-of-stainless-steels.md) — Extract from standard DIN EN ISO 3506. Steel groups and strength classes are designated by a sequence of letters and numbers consisting of 4 characters. The letters denote the general classification of the steel groups: A = austenitic steels, C = martensitic steels, F = ferritic steels. - [20 points to follow to prevent galling of austenitic (stainless and acid-resistant) screws](https://menet-trend.hu/en/nonox-world/20-points-to-follow-to-prevent-galling-of-austenitic-stainless-and-acid-resistant-screws.md) — Galling of stainless and acid-resistant screws is not caused by a material defect, but by mechanical irregularities and/or failure to follow the assembly technology. You can find out here, point by point, what that technology is: handle the screws carefully, and avoid every possibility of mechanical damage to them. - [Angle grinder test](https://menet-trend.hu/en/nonox-world/angle-grinder-test.md) — First impressions.
