Author: Various edited by John Murphy Soft Cover Magazine Review by Bill Curtis Initial assessment Well this is the third edition of the Weathering Magazine from A.K. Interactive and I have to say this is as good as the previous two volumes with clear pictures printed on glossy paper with clear concise text with 88 pages. This is not all you get in this edition as John Murphy runs through the methods of applying Chipping using Hairspray, Salt, Chipping Fluid, Decals and masking fluids. This is followed by SBS showing how to use these items with the inclusion of sponge and brush techniques. Next we are treated to a micro chipping article on an M32 recovery vehicle explained by Wu Bayin. Another Japanese Aircraft is done by Jose L Echaide is a photo double page items what shows what can be done with chipping fluid. John Tolcher shows how to chip using the hairspray technique on the cab of a Steyr.
A three page article on how chips and scratches can be applied to metal items used on figures is explained by Cesar Oliva. Chuck Doan takes us through how to replicate peeling paint on a wood base and has a couple of half page photographs of some Dio settings. Jamie Haggo has another two page SBS on chipping A FW 190 cockpit both with Chipping fluid and Maskol. Gunner Baumer shows how to chip a Pak 43/41 in an article called chipping the barn door as this was one big Anti tank gun.
The Weathering - Issue 6English| 88 pages| True PDF| 79.00 Mb. Disclaimer: This site does not store any files on its server. We only index and link to content provided by other sites. This version of the magazine is intended to familiarize!
Lester Plaskitt then shows how to weather a Sdkfz 251 Drilling using techniques that could be used on many other vehicles. The final techniques article is by David Marti who uses a turret to demonstrate the salt technique and the final washes fading and pigments to show what a realistic look it has. There is four pages of reference photographs showing various chips and scratches, a further two pages show models from around the world this time from Greece. It wouldn’t be right not to mention the Model who adorns several pages throughout this issue. I am of course talking about Akatsiya who is female long legged and has no scratches or chips that I can see.
Conclusions Stunning yet again with super clear pictures, good SBS with easy to follow text. I am already wanting the next issue which is to be devoted to engines. Very Highly Recommended Purchased from Bill C. Primary Sidebar.
Weathering steel – Fulcrum (1987) by Weathering steel, often referred to by the COR-TEN steel and sometimes written without the hyphen as corten steel, is a group of alloys which were developed to eliminate the need for painting, and form a stable -like appearance after several years exposure to weather. Holds the on the name COR-TEN. The name COR-TEN refers to the two distinguishing properties of this type of steel: corrosion resistance and tensile strength. Although USS sold its discrete plate business to (now ) in 2003, it still sells COR-TEN branded material in strip-mill plate and sheet forms. The original COR-TEN received the standard designation A242 (COR-TEN A) from the standards group.
Newer ASTM grades are A588 (COR-TEN B) and A606 for thin sheet. All alloys are in common production and use. The surface oxidation of weathering steel takes six months, but surface treatments can accelerate the oxidation to as little as two hours. Contents. Properties Weathering refers to the chemical composition of these steels, allowing them to exhibit increased resistance to atmospheric corrosion compared to other steels.
This is because the steel forms a protective layer on its surface under the influence of the weather. The corrosion-retarding effect of the protective layer is produced by the particular distribution and concentration of alloying elements in it. The layer protecting the surface develops and regenerates continuously when subjected to the influence of the weather.
In other words, the steel is allowed to rust in order to form the protective coating. Chemical composition of Weathering steel grades (%, besides iron) Grade ASTM A242 0.12 0.25–0.75 0.20–0.50 0.01–0.20 0.030 0.50–1.25 0.25–0.55 0.65 ASTM A588 0.16 0.30–0.50 0.80–1.25 0.030 0.030 0.40–0.65 0.25–0.40 0.02–0.10 0.40 The mechanical properties of weathering steels depend on which alloy and how thick the material is. ASTM A242 The original A242 alloy has a of 50 (340 ) and of 70 ksi (480 MPa) for light-medium rolled shapes and plates up to 0.75 inches (19 mm) thick. It has yield strength of 46 ksi (320 MPa) and ultimate strength of 67 ksi (460 MPa) for medium weight rolled shapes and plates from 0.75–1 inch (19–25 mm) thick. The thickest rolled sections and plates – from 1.5–4 in (38–102 mm) thick have yield strength of 42 ksi (290 MPa) and ultimate strength of 63 ksi (430 MPa). ASTM A 242 is available in Type 1 and Type 2.
Both have different applications based on the thickness. Type 1 is often used in housing structures, construction industry and freight cars. The Type 2 steel which is also called Corten B is used majorly in urban furnishing, passenger ships or cranes. ASTM A588 A588 has a yield strength of at least 50 ksi (340 MPa), and ultimate tensile strength of 70 ksi (480 MPa) for all rolled and plate thicknesses up to 4 in (100 mm) thick. Plates from 4–5 in (102–127 mm) have yield strength at least 46 ksi (320 MPa) and ultimate tensile strength at least 67 ksi (460 MPa), and plates from 5–8 in (127–203 mm) thick have yield strength at least 42 ksi (290 MPa) and ultimate tensile strength at least 63 ksi (430 MPa). The rate at which some weathering steels form the desired patina varies strongly with the presence of atmospheric pollutants which catalyze corrosion.
While the process is generally successful in large urban centers, the weathering rate is much slower in more rural environments., a social sciences building on 's main campus in, a small town in, did not achieve the predicted surface finish on its Mayari-R weathering steel framing within the predicted time. Rainwater runoff from the slowly rusting steel stained the numerous large windows and increased maintenance costs. Corrosion without the formation of a protective layer apparently led to the need for emergency structural reinforcement and galvanizing in 1974, less than two years after opening. The in was constructed by in part to showcase COR-TEN steel. The initial weathering of the material resulted in a discoloration of the surrounding city sidewalks which is known as 'bleeding' or 'runoff', as well as other nearby buildings. A cleanup effort was orchestrated by the corporation once weathering was complete to clean the markings. A few of the nearby sidewalks were left uncleaned, and remain a rust color.
This problem has been reduced in newer formulations of weathering steel. Staining can be prevented if the structure can be designed so that water does not drain from the steel onto concrete where stains would be visible. References.
